Abstract
PURPOSE: To surely commutate a converter, by supplying the converter with gate pulses, each of which is a pulse with a large width of 120° or a pulse comprising at least four small-width pulses within 120°.
CONSTITUTION: A converter 3 is commutated by gate pulses Up1, Vp1, Wp1. At that time, a voltage EU-W is distorted. When commutation from a phase Wp to another Up is effected, the voltage EU-W becomes zero. Even if a gate signal for another converter 9 changes to a different phase during the zero-voltage period, the converter 9 is not commutated because there is no commutating power during the period. When the commutation of the converter 3 is finished, power voltage recovers. As a result, the converter is commutated if the gate signal has a large width. If the gate signal for the converter 9 does not start during the commutation period of the converter 3, the commutation of the converter 9 begins when the gate signal is entered into it.
