一种低待机功率电路的设计

Design of Lower Standby Power Circuit

分析了在隔离型电源设计中传统自举电路待机功耗存在的问题,介绍了一种可降低待机功率的自举电路,并给出了详细的实验电路和参数及实验结果。该电路在上电后消耗很少甚至几乎不消耗能量,成功解决了低待机功率的问题。

Problems were analyzed on the standby power loss of traditional bootstrap circuit in the isolation power source design.A bootstrap circuit was introduced hereby,which can reduce the standby power.The detailed experimental electric circuit,the parameter and the experimental result were also presented.The circuit dissipated little to no energy after power up to solve the lower standby power problem successful.
