Abstract
PURPOSE:To certainly suppress pulsating current caused by voltage due to counter-electromotive force, by detecting the conduction phase of a power inverter, and by feeding back the counter voltage due to electromotive force corresponding to the conduction phase feeding forward to the current control system of a power rectifier. CONSTITUTION:The delays of the output signal of a phase power rectifier 13 for detecting the conduction phase of a power inverter 3, and gate pulse signal from a gate pulse generator 16 are compared with each other. By a reasonableness checking circuit, it is checked whether the delays are abnormal or not, and its result is applied to a signal selecting circuit 15. By the signal selecting circuit 15, from line voltage obtained from a three-phase voltage transformer 12, voltage corresponding with conduction phase detected by the phase power rectifier 13 is selected, and is fed to an adder 9, and is added to the input signal of a gate pulse generator 10 for a power rectifier.
