Then the power circuit is designed. at last, with analysis of experiment data the relation of power output and transmission efficiencyoftransformer is researched in detail.
The results proved that the improved resonant mode load current is close to sine wave. The energy transfer efficiencyoftransformer is improved by 3 percent, and the EMI is decreased.
