Claims (1)
挿したチョッパの通流率制御を行う制御装装置において
、前記交流電源に変成器を介して単相ダイオードブリッ
ジ回路を接続し、この単相ダイオードブリッジ回路の出
力端が得られる単相整流波形電圧信号と直流出力電圧制
御信号とを比較し単相整流波形電圧信号が直流出力電圧
制御信号より大きくなる偏差を生じる時間において出力
信号を発生するコンパレータを設け、このコンパレータ

ことを特徴とするチョッパの制御装置。In a control device that controls the conduction rate of a chopper inserted between a main rectifier and a load circuit connected to an AC power supply, a single-phase diode bridge circuit is connected to the AC power supply via a transformer, The output terminal of this single-phase diode bridge circuit compares the single-phase rectified waveform voltage signal obtained from the DC output voltage control signal and outputs the signal at the time when a deviation occurs in which the single-phase rectified waveform voltage signal becomes larger than the DC output voltage control signal. What is claimed is: 1. A chopper control device comprising: a comparator that generates a signal; and an output signal of the comparator is directly applied to the chopper as an energizing signal.
