Chopper voltage regulator is a new working mode of voltage stabilizing scheme, chopping chopped switch circuit with pulsating wave, and compensating by DC voltage negative feedback. Transistor chopper regulator: series regulator of the traditional four point change, make it become the switch circuit, maintains the advantages of simple circuit, less components, low cost, high voltage precision, small resistance, and has the advantages of high efficiency, high voltage, no radio interference. Twenty million birds designed with chopper type power supply of color TV, may switch pulse width O & - switch power supply challenge.

斩波式稳压其特征是将整流后不经滤波的(或其他来源的)脉动波采用开关电路进行定量斩波,即输入电压与负载之间接入开关电路,在输入电压超过某瞬时值时即阻断,此前的电压全部被负载所得到;负载上的电压即输出电压的波形是中间有缺口、剩余部分与输入电压波形相应部分相符;在输入电压数值变动时,输出电压的峰值不变但有效值则有所变动,再采用直流电压负反馈加以补偿,便可得到稳压精度高、内阻小的特性。
