Multi resonant control of high frequency link inverter

A muti resonant controller for high-frequency-link single-phase inverter is proposed in this paper. An equivalent circuit, which behave just like conventional unipolar PWM inverter is proposed for the converter. The dynamic model of the inverter, which built in continuous domain, is built. The inverter has the advantages of high efficiency, high power density, low-cost, low noise, bidirectional power flow and wide range of output voltage, etc. muti resonant scheme for this inverter is developed, which achieved low THD under resistance load and diode rectifier load. Simulation results are provided to testify the effectiveness of the proposed scheme.
