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

Figure 1: Typical EV power conversion elements

Ask any power electronics designer what they strive for and top of the list is normally conversion efficiency. It’s not just for energy savings but also the knock-on benefits of smaller, lighter and cheaper products, with options opening up for better reliability and more functionality in space that’s freed-up. So

Figure 1: Si, SiC and GaN material characteristics

A basic building block in power conversion electronics is the semiconductor switch. The ideal is one with no static or dynamic losses that can withstand high voltage in the off state and with no leakage when on – but that is always just out of reach. One of the closest though is the wide band-gap technology Si
