Selectively Controlled Electrical Power Switching System

摘要

Electrical energy from a DC voltage source is supplied through a power switchingconverter under operational control, to an electrical load in accordance with a soft switching mode implemented by an auxiliary resonant commulated pole inverter. A mode control section having snubber switches connected to the switching converter selectively changes switching operation to a hard switching mode so as to accommodate supply of load current at higher levels to the electrical load.
