Description
演算部51は、PWM信号の生成等を行うマイクロプロセッサである。演算部51は、PWM出力ポート511、停止信号出力ポート512、フォルト信号入力ポート513、PWM入出力ポート514、切替信号出力ポート515を備える。
例えば、直流電源1の過電圧を検出する過電圧フォルト信号が発生するような過電圧検出器がある構成において、演算部51が正常と判断する直流電源電圧よりも低い領域で冗長PWM信号の出力を許可するようにする、または、出力電流に制限をつけるようにする。このとき、「過電圧検出器動作電圧>演算部51が判断する正常電圧>冗長PWM信号の出力制限電圧」という関係になる。直流電源1の過電圧の兆候を早めに捉え、出力を制限することにより過電圧による故障に至らないようにする。なお、冗長PWM信号は第2バッファ部53から出力される保護動作PWM信号よりも優先度が高くなるように設定されている。フィードバック部55は、故障検出部54からPWMフォルト信号が入力された場合に、冗長PWM信号を遮断する。
(1)インバータ制御部5は、モータ3を制御するためのPWM信号を出力する演算部51と、演算部51より出力されたPWM信号を第1バッファ部52を介して受信し、受信したPWM信号に基づいてインバータ回路2を駆動する駆動部6と、第1バッファ部52から出力されるPWM信号を受信し、受信したPWM信号を演算部51へフィードバックするフィードバック部55と、を備え、演算部51は、第1バッファ部52が故障した場合に、フィードバック部55を介して冗長PWM信号を駆動部6へ出力する。これにより、PWM信号を出力する第1バッファ部52に故障が発生しても、より信頼性が高いインバータ制御装置を提供できる。
