Abstract

【課題】交流変換制御回路及び装置を提供する。【解決手段】交流変換制御回路は、電圧フィードバック回路９、電流フィードバック回路１５、第１の駆動回路８、電圧検出回路１０、電流検出回路１２、第２の駆動回路１１及び主制御回路１４が設けられて、交流変換制御を実現する。具体的に、主制御回路を回路全体の主制御センターとし、主制御回路は、電圧フィードバック回路、電流フィードバック回路の入力信号に基づいて第１の駆動回路の動作を制御し、さらにＤＣ−ＤＣ変換回路６の動作を制御し、また、主制御回路は、電圧検出回路、電流検出回路の入力信号に基づいて第２の駆動回路の動作を制御し、さらにＤＣ−ＡＣ変換回路７の動作を制御して、ＡＣ−ＡＣ変換に対する制御を実現し、回路の構造が簡単で、前後段のフィードバック制御が設けられることにより、回路の信頼性が高く、動作安定性が高い。【選択図】図１An AC conversion control circuit and apparatus are provided. An AC conversion control circuit includes a voltage feedback circuit, a current feedback circuit, a first drive circuit, a voltage detection circuit, a current detection circuit, a second drive circuit, and a main control circuit. As a result, AC conversion control is realized. Specifically, the main control circuit is the main control center of the entire circuit, and the main control circuit controls the operation of the first drive circuit based on the input signals of the voltage feedback circuit and the current feedback circuit, and further performs DC-DC conversion. The operation of the circuit 6 is controlled, and the main control circuit controls the operation of the second drive circuit based on the input signals of the voltage detection circuit and the current detection circuit, and further controls the operation of the DC-AC conversion circuit 7. Thus, the control for AC-AC conversion is realized, the circuit structure is simple, and the feedback control of the front and rear stages is provided, so that the reliability of the circuit is high and the operation stability is high.
