Today at the Applied Power Electronics Conference (APEC), Infineon Technologies AG introduced a new product family of Solid-State Isolators (iSSI) to achieve faster and
more reliable circuit switching with protection features not available in optical-based solid
state relays (SSR). iSSI use coreless transformer technology and support 20 times greater
energy transfer with both current and temperature protection contributing to a higher
reliability and lower cost of ownership. The new iSSI allow driving the gates of Infineon’s
MOS-controlled power transistors OptiMOSTM and CoolMOSTM to reduce power dissipation
of up to 70 percent of todays’ solid-state relays using SCR (silicon-controlled rectifier) and
Triac switches.

Infineon’s solid-state isolators enable custom solid-state relays capable of controlling loads
more than 1000 V and 100 A. Improved performance and reliability make coreless
transformer technology ideal for applications in advanced battery management, energy
storage, renewable energy systems, as well as industrial and building automation system
applications. With iSSI drivers, engineers can further improve the efficiency of electronic
and electromechanical systems.

“Implementing coreless transformers in solid-state isolators and relays is truly a game-
changer for power engineers; it provides 50 times lower RDS(on) than existing optically controlled solutions. This enables their use in higher-voltage and higher power applications,” said Davide Giacomini, Marketing Director for the Green Industrial Power
Division at Infineon Technologies.

When matched with Infineon’s CoolMOS S7 switch, the iSSI drivers enable switching
designs with a much lower resistance compared to optically driven solid-state solutions.
This translates to longer lifespans and lower cost of ownership in system designs. As with
all solid-state isolators, the devices also offer superior performance compared to
electromagnetic relays, including 40 percent lower turn-on power and increased reliability
due to elimination of moving parts.

The family of devices is designed to be compatible with Infineon’s broad switching portfolio
including Infineon’s CoolMOS S7, OptiMOSTM and linear FET portfolios.

In the realm of lighting, one of the most iconic and enduring symbols is the filament bulb. While newer technologies have emerged, the filament bulb continues to hold a special place in our hearts and homes. In this blog, we delve into the world of filament bulbs, exploring what they are, how they work, their uses, and their advantages.

What is a Filament Bulb?

A filament bulb, also known as an incandescent bulb, is a type of light bulb that produces light by heating a thin tungsten wire filament to a high temperature until it glows. The filament is housed within a glass bulb filled with inert gas to prevent the filament from oxidizing and burning out too quickly.

How Does a Filament Bulb Work?

The principle behind the operation of a filament bulb is simple yet elegant. When an electric current passes through the filament, it encounters resistance, which causes the filament to heat up. As the temperature rises, the filament emits light in the visible spectrum, illuminating its surroundings.

Filament Bulb Uses

Filament bulbs have been a staple in lighting applications for over a century. While their popularity has waned with the advent of more energy-efficient alternatives, filament bulbs still find use in various settings, including:

1. Decorative Lighting: Filament bulbs are prized for their warm, inviting glow, making them a popular choice for decorative lighting in homes, restaurants, and cafes.
2. Vintage Aesthetics: With their classic design and nostalgic appeal, filament bulbs are often used in vintage-inspired interiors, adding a touch of old-world charm.
3. Display Lighting: Filament bulbs are ideal for highlighting merchandise in retail displays, creating an attractive ambience that draws customers’ attention.
4. Special Events: From weddings to outdoor parties, filament bulbs are a popular choice for creating a festive atmosphere, casting a warm and inviting glow over gatherings.

Filament Bulb Advantages

While filament bulbs may not be as energy-efficient as their LED counterparts, they still offer several advantages that make them a preferred choice in certain scenarios:

1. Warmth and Ambiance: Filament bulbs emit a warm, soft light that closely resembles natural sunlight, creating a cozy and inviting atmosphere wherever they are used.
2. Instant On: Unlike some energy-saving bulbs that require time to reach full brightness, filament bulbs provide instant illumination, making them ideal for areas where immediate light is needed.
3. Dimmable: Many filament bulbs are dimmable, allowing users to adjust the brightness to suit their preferences and set the mood for different occasions.
4. Affordability: Filament bulbs are often more affordable than LED bulbs, making them a cost-effective lighting solution for those on a budget.
5. Compatibility: Filament bulbs are compatible with most standard fixtures, making them an easy and convenient replacement for traditional incandescent bulbs.

In Conclusion

While filament bulbs may no longer be the go-to choice for energy-conscious consumers, their timeless appeal and unique characteristics continue to make them a popular lighting option in many settings. Whether used for decorative purposes, vintage aesthetics, or special events, filament bulbs shine bright as a symbol of illumination’s enduring legacy.

A corresponding ecosystem of support tools will help simplify motor control system development and accelerate time to market

To implement efficient, real-time embedded motor control systems in space-constrained applications, Microchip Technology has launched a new family of dsPIC Digital Signal Controller (DSC)-based integrated motor drivers. These devices incorporate a dsPIC33 digital signal controller (DSC), a three-phase MOSFET gate driver and an optional LIN or CAN FD transceiver into one package. A significant benefit of this integration is reduction in component count of the motor control system design, smaller printed circuit board (PCB) dimensions and reduced complexity. The devices are supported by development boards, reference designs, application notes and Microchip’s field-oriented control (FOC) software development suite, motorBench Development Suite V2.45.

“Automotive, consumer and industrial designs are evolving and require higher performance and reduced footprints. These expectations often come at a higher expense and increase in dimensional size,” said Joe Thomsen, vice president of Microchip’s digital signal controllers business unit. “By integrating multiple device functions into one chip, the dsPIC DSC-based integrated motor drivers can reduce system-level costs and board space.”

The integrated motor driver devices can be powered by a single power supply up to 29V (operation) and 40V (transient). An internal 3.3V low dropout (LDO) voltage regulator powers the dsPIC DSC, which eliminates the need for an external LDO to power the device. Operating between 70—100 MHz, the dsPIC DSC-based integrated motor drivers provide high CPU performance and can support efficient deployment of FOC and other advanced motor control algorithms.

High-precision metrology solutions are not only an opportunity to optimize the manufacturing process but also offer valuable insight into material sciences and ensure the quality of the output.

Additive Manufacturing as an Opportunity in Aerospace

Air travel, a preferred mode of transportation, relies on aircraft parts meeting stringent quality standards. For instance, before a supplier commences production, up to 1500 inspection features of a turbine blade must be verified, adhering to tight tolerance ranges at every production step. Beyond this challenge, another is the vital maintenance and repair operations (MRO) which often involves replacing high-complexity, quality-intensive low-volume or single parts. Traditional manufacturing processes for MROs prove both time and cost-intensive, unable to meet the demanded complexity and accuracy efficiently. Consequently, additive manufacturing, specifically 3D printing, is increasingly integrated into the aerospace production chain in India, positioning the industry as a pioneer in additive manufacturing innovation. However, the adoption of this technology brings its own challenges, which our experience suggests can be effectively addressed through high-quality metrology solutions.

Hitting the Brake: The Process and Challenges of Additive Manufacturing

Powder is the building block of additively manufactured parts. The particles are small, typically ranging from a few micrometers to tens of microns in diameter. Their size distribution and shape influence spread ability and hence possible defects might occur during the process. The defect density is among other aspects and also a factor for the recycling and aging of the powder. A uniformly distributed powder bed is the essential basis for a stable and reliable additive manufacturing process. Improper powder quality, powder rheology and the process parameters might cause voids to form in the final structure. The additive manufacturing process, unlike traditional manufacturing methods, requires powders to be melted layer by layer during the build. Melt temperatures and process parameters greatly affect the crystallography and, as a consequence, part properties. After printing, the part is still attached to the build plate. It is then heat-treated for stress relief and removed from the build plate with a band saw or wire EDM. Some parts are then heat treated again for microstructure changes. These processes possibly influence the characteristics and accuracy of the part, impacting the quality and safety. Post which, Dimensional accuracy and surface finish are critical to ensure proper assembly and consistent matching across multiple parts. Even though additive manufacturing is an immense opportunity since it enables an unprecedented control over material microstructures. Analyzing and understanding these structures is key for an efficient and optimized process that ensures the demanded quality and safety.
