【 摘 要 】

This paper explains Field-programmable gate array (FPGA) based digital control of DC-DC phase shifted full bridge converter operating at very high switching frequency. To achieve required high switching frequency, theoretically very high clock frequency is needed but how to achieve with less clock frequency has been shown here. The implementation in FPGA includes control algorithm and hybrid Digital Pulse Width Modulator (DPWM). Microsemi’s Proasic3E FPGA is used for implementation with 32 MHz clock frequency to achieve required 1 MHz switching frequency.
