| description | To reduce output power error and input current distortion occurring by commutating state.SOLUTION: A control arrangement of power conversion equipment performing state control of each switch element in the power conversion equipment so that the power conversion equipment transits from the switch state of commutation source to the switch state of commutation destination via the commutating state includes an expansion amount calculation part 103 for calculating the expansion amount Don the basis of the zero-cross occurrence timing, i.e., the zero-cross timing of a current flowing through a reactor while the power conversion equipment 1 is in the commutating state, and the end timing of the commutating state, and a control section 104 for delaying the timing for performing state control of each switch element on the basis of the expansion amount Dafter ending the commutating state.SELECTED DRAWING: Figure 16
【課題】転流中状態によって発生する出力電力誤差や入力電流歪みを低減する。【解決手段】電力変換装置が転流元のスイッチ状態から転流中状態を経て転流先のスイッチ状態に遷移することとなるよう電力変換装置内の各スイッチ素子の状態制御を行う電力変換装置の制御装置であって、電力変換装置１が上記転流中状態にある間にリアクトルを流れる電流がゼロクロスするタイミングであるゼロクロス発生タイミングと、上記転流中状態の終了タイミングとに基づいて延長量Ｄｃｏｍ１を算出する延長量算出部１０３と、延長量Ｄｃｏｍ１に基づいて、上記転流中状態の終了後に上記各スイッチ素子の状態制御を行うタイミングを遅延させる制御部１０４とを備える。【選択図】図１６ |
