The compactness, speed, performance can be achieved in power inverters by using Silicon Carbide (SiC) transistors instead of silicon power transistors. The Japanese power electronics company Mitsubishi Electric has launched a working model of what it calls as “ultracompact inverter” for hybrid electric vehicles designed using Silicon Carbide transistors.
The power semiconductor devices in this module are connected to heatsink with solder. The space-saving inverter is designed to meet lesser physical space requirements in a hybrid car, which are designed to meet stringent fuel efficiency regulations.
Mitsubishi to develop this product further and planned to commercialise in the year 2021.
