Abstract:
This paper proposes a zero-voltage-transition (ZVT) buck converter with synchronous rectifier (SR). The conduction losses due to rectifying diode can be reduced by SR but the reverse recovery time of SR body diode will increase switching losses and electromagnetic interference (EMI). So soft switching techniques are employed. In this converter zero voltage switching (ZVS) is achieved for main switch and SR. Also zero current switching (ZCS) for auxiliary switch. The ZVT synchronous buck converter is analyzed and simulation results are obtained.
