二极管的整流应用就是利用二极管的单向导电特性将交流电变为直流电的过程。常用的单相整流电路可分为单相半波、全波、桥式和倍压(升压)四种,下面分别加以介绍。1.单相半波整流:电路由一个二极管组成,由于二极管的单向导电性,在所供交流电变化一周时,负载上只有半个周期有电流流过,所以叫半波整流。图1为半波整流电路。图中 D 为半波整流作用 Diode rectifier application is the use of one-way diode conduction characteristics of the AC to DC into the process. Commonly used single-phase rectifier circuit can be divided into single-phase half-wave, full-wave, bridge and times the pressure (boost) four, the following were introduced. 1. Single-phase half-wave rectifier: The circuit consists of a diode, due to the diode unidirectional conductivity, the change in the supply of AC for a week, the load only half a cycle of current flow, so called half-wave rectification. Figure 1 for the half-wave rectifier circuit. D for the half wave rectification
