Abstract

In this paper, a new constant-frequency LL switch-capacitor (LLSC) quasi-resonant converter is proposed. Compared with the traditional frequency voltage regulation instruments, the proposed converter can effectively reduce the volume of magnetic components. A switch-control capacitor is used in the LLSC converter and adjusts the capacitor parallel anti-series MOSFET turn-ON delay to change the equivalent capacitance. At constant frequency, the output voltage is adjusted by impedance adjustment. The LLSC converter can achieve the primary side MOSFET zero-voltage switching. A new design procedure is proposed for the LLSC converter. The proposed converter is experimentally by experimental results using 80-120 V and 250-W output prototype.
