Design of rectifier regulator of permanent magnet generators for agricultural machinery

设计的单相桥式全波整流调节器由全波整流电子电路和电压调节电子电路两部分组成,其中,4只二极管(D1、D2、D3、D4)组成桥式整流电路,起到将发电机电枢绕组产生的交流电转变成直流电的作用;电压调节电子电路由电阻、电容、三极管、稳压管、晶闸管等电子元件组成,它起到稳定输出电压的作用,可保证发电机输出电压稳定的直流电,解决永磁发电机在转速、负载变化幅度大时输出电压不稳定的问题。

The single-phase bridge type full-wave rectifier regulator was consisted by two parts, full-wave rectifier circuit and voltage regulating electronic circuit. The bridge type full-wave circuit was composed by four diodes （D1 、D2、D3、D4）, which could transfer the AC created by armature winding to DC. The voltage regulating electronic circuit included the resistance, capacitance, triode, stabilivolt, thyristor and other electronic components, which could make the output voltage stable and guarantee the generator output stable voltage DC. It solves the voltage output instability problem when the permanent magnet generators in large speed and load changes.
