ABSTRACT:
In a commutation control device for a current type inverter, a device for detecting voltage of a commutation capacitor and a device for controlling a charging interval of the capacitor are provided. The voltage detecting device includes a comparator, while the charging interval control device includes a timing pulse generator, a circuit for delaying a pulse delivered from a pulse generator, and a timing signal generator which delivers a timing signal adapted to control a discharge interval of the commutation capacitor for restricting the voltage thereof in a predetermined range.
