Full Digitalized ZVZCS control technique for high-frequency link inverter

This paper proposes DSP based digital control technique for high-frequency link inverter which has advantages such as high power density , high conversion efficiency and bi-directional power flow capability. The proposed control technique is easy to be realized with digital signal processor (DSP) and switches of high-frequency inverter can be realized with ZVS on and off. while the switches of cycloconverter are ZVS on and ZVZCS off. Detailed operation modes are discussed. This digital control technique is verified by simulation results and experimental results of 300 VA prototype fully controlled by the DSP controller TMS320F2407
