A Characteristic Analysis of Instantaneous Voltage Resultant Control-Based Double Full-Bridge High Frequency Inverter

순시전압 합성제어형 2중 풀 브릿지 고주파 인버터 특성 해석

This paper describes a study on the series resonant inverter using the double full-bridge, and the output voltage of the proposed inverter is controlled by phase shift angle of the outputs of two inverters. These control schemes can be reduce the switching loss and EMI, etc, which the inverter is drived by auto following control of output frequency, because it is impossible for switching devices to be always turned on and off at zero voltage or zero current. Theoretical characteristics of the proposed double inverter circuit are compared with Pspice simulation and experimental results.
