| Abstract: | This paper presents a digital controlled soft -switching power supply, which is based on sliding-mode control method by using FPGA（FLEX10KA）. This active clamp forward power supply is designed for satisfying 180 W load capacity need. The controlled time sequence of the power supply and the sliding mode variable-structure control method are analyzed in detail From the experimental results we can see clearly that the sliding mode control system has high robustness, system stability and fast dynamic response; especially realized ZVS（Zero-vohageswitching） of switching tube of main circuit. |
