Abstract

PURPOSE: For preventing the dispersion of parts in characteristic and the influence of the frequency for example of power supply, to apply ignition pulses on the first and second phase control type rectifier devices connected in anti-parallel to each other in synchronization with the zero point of power supply voltage.
CONSTITUTION: First and second phase control type rectifier devices 5 and 16 are provided in anti-parallel to each other between given terminals for three-phase power supply. Said first phase control type rectifier device 5 is ignited in synchronization with the zero point of the voltage between said given terminals. When said first phase control type control rectifier device 5 has transferred from continuity to non-continuity, said second phase control type rectifier device 16 is ignited by the energy of said three-phase power supply.
