Design for a intermediate frequency power supply in 20 kHz/10 kW. In the power supply, a three-phase uncontrolled rectifier and the series resonance inverter is applied. The parameters of main circuit＇s devices are given and through simulink simulation provides basis for experiment device. Then according to the requirements of IGBT, we choose the IGBT driving circuit SKHI 22 A and research in detail on IGBT drive circuit and its peripheral circuit design. A phase-locked control is realized with the integrated phase-locked loop CD4046 and the digital signal processor DSP, so that the load power factor of the power supply can be always kept to unity. This digital phase locked loop has high stability. Experiment results show the feasibility of this design.
