エネルギーを抵抗に消費させ、又入力電源を切つ
た時コンバータ部の平滑コンデンサに蓄積された
電荷を抵抗にて放電させる回転機駆動制御装置に
おいて、回生エネルギーを抵抗消費させるために
抵抗に流す電流を制御するパワートランジスタと
並列に設けたコンタクタにより入力電源を切つた
時パワートランジスタのコレクタ−エミツタ間を
短絡することを特徴とする回転機駆動制御装置。 In a rotating machine drive control device, regenerative energy from a motor controlled by a voltage source inverter is consumed in a resistor, and when the input power is turned off, electric charges accumulated in a smoothing capacitor in the converter are discharged by a resistor. A rotating machine drive control device characterized in that a contactor provided in parallel with a power transistor that controls current flowing through a resistor for consumption causes a short circuit between the collector and emitter of the power transistor when the input power is turned off.
