Soft-switch Technology Based on High-frequency Link Parallel Inverter

The inverter as the core of the High-frequency inverter linked parallel system to achieve the soft switching characteristics,reduce the switching losses is a priority of system research.The main circuit using FB-ZVZCS(full-bridge zero-voltage and current)soft-switch topology,with the outer ring voltage current inner ring double-loop control system,achieves a soft switching inverter.Adopting improved control of the PQ,effectively improve the load flow results.Simulation shows that the inverter has a good performance.
