摘要: This paper proposes a simple asymmetric half-bridge converter structure, which operates without any DC offset of the transformer magnetizing current. The proposed topology has modified rectification stage comprising only one diode and hence offers advantages reduced device count improved efficiency. Detailed theoretical analysis circuit operation is presented followed by simulation experimental results on 240 W Laboratory prototype.
