The increasing demand for high power density is pushing developers to adopt 1500VDC links in their applications to increase the rated power-per-inverter and reduce system costs. However, 1500VDC-based systems also pose more challenges on the system design, such as fast switching at high DC voltage, which typically requires a multi-level topology. This leads to a complicated design and a relatively high number of components...
