Chinese manufacturer Sungrow has introduced a new utility string inverter, a three-phase hybrid inverter for commercial and industrial (C&I) applications, and a liquid-cooled energy storage system.
For the past two decades, Insulated Gate Bipolar Transistors (IGBTs) and their associated silicon (Si)-based Free Wheeling Diodes (FWDs) have been the mainstay switching devices in 3-phase inverters.
