1500V Power Module Doubles Up for Both Solar and Storage Use
This is partly due to packaging requirements and partly due to the bespoke requirements for individual use cases. This drives up the cost of components for high-power applications as there is very little economy of scale. Infineon has tried to buck this trend somewhat with its new EasyPACK CoolSiC MOSFET module that
