1.Overview
A three-phase VSI typically consists of two major components, the first of which is a DC voltage source. The DC volta
source can come from a storage bank such as a battery, a supercapacitor, or the output of a previous DC-DC convert
DC-link capacitor after the input DC voltage source may be required in some cases to maintain a constant voltage ac
the inverter and protect it from voltage spikes, surges, and electromagnetic interference (EMI).
