摘　　要：微功耗直流稳压器采用电压切割和电压补偿的方法,实现了对直流电压的稳定或调整,该直流稳压器最大特点是,主电路不采用PWM脉宽调制,不产生EMI干扰,因此功耗极小而寿命极长,输出直流电压调整率高,效率高达99.5%,安全可靠,节能环保,电路简单,制作安装容易,其成本、体积、重量、功耗都是传统直流稳压器的十分之一。The voltage interception and voltage compensation was employed to stabilize or regulate DC voltage, whose distinguished characteristic is that the core ＇circuit could avoid the electro-magnetic interferences （EMI） to the grid for no use of pulse-width modulation （PWM）. Therefore its power consumption is kept as low as possible while its lifetime can be as long as possible with an efficiency as high as 99.5%. Moreover, it is safe and reliable, green and energy-conserving and its simple circuit is easy to fabricate. Its cost, volume, weight, and power consumption are about only ten percent of those of the traditional DC voltage regulators.
