摘　　要：文中详细分析了不对称半桥变压器直流偏磁产生的原因,讨论了利用次级不对称绕组和倍流整流两种方式解决偏磁问题的方法,最后给出仿真结果。The theoretical analysis of DC bias current in transformer of asymmetrical half bridge is presented in this paper. Then the methods using unbalanced transformer and using current-double rectification which can reduce the DC bias are introduced, the results of simulation are also given finally.
