3-PHASE IHCML INVERTER

摘要

A three phase IHCML inverter is provided to control frequency in two transformers having each different transformation ratio and improve the product quality of output voltage with less switch loss. A switching unit(120) comprises three H-bridge(121) of parallel. The switching unit outputs the voltage of constant frequency by receiving DC power. A transformer(131,132) comprises 3-phase transformer. The transformer has an output terminal directly connected with output of 3-phase transformer.
