Abstract: An impulse commutated inverter is provided with control apparatus for firing a first commutating rectifier, sensing the subsequent flow of capacitor overcharge current in a parallel reset resistor and delaying a fixed time interval after current flow is first sensed before an opposite serially connected commutating rectifier is permitted to fire. The inverter is thus allowed to generate minimum pulse widths to achieve the maximum possible output voltage in pulse width modulation operation without increasing the risk of shoot-through resulting from simultaneous conduction of the two commutating rectifiers.
