Abstract
Description
制御部20は、スイッチ部23A、23Bの一方をオンし、他方をオフにする。また、制御部20は、後述の異常判定処理の結果に応じて、スイッチ部23A、23Bのオンとオフとを切り替える。例えば、制御部20は、スイッチ部23Aをオンし、スイッチ部23Bをオフしている場合、異常判定処理の結果によって、スイッチ部23Aをオフし、スイッチ部23Bをオンする。つまり、制御部20は、コンバータ部103に接続する商用電源を、商用電源101Aから、商用電源101Bへ切り替える。
制御部20は、コンバータ部103への入力電圧の異常を判定する。入力電圧の異常とは、切替部102によりコンバータ部103に接続されている商用電源101Aまたは商用電源101Bの異常である。以下では、切替部102により商用電源101Aがコンバータ部103に接続されていて、制御部20は、商用電源101Aの異常を判定するものとして説明する。つまり、スイッチ部23Aがオン、スイッチ部23Bがオフである。
制御部20は、異常判定処理を実行する時間(以下、判定時間という)を、電流検出部107が検出する電流値に基づいて調整する。制御部20は、電流検出部107が検出する電流値、すなわち、負荷電流から、負荷104の軽重を判定する。そして、負荷104が軽い場合には、制御部20は判定時間を長くする。一方、負荷104が重い場合には、制御部20は判定時間を短くする。
