Abstract :
A new pulsewidth modulation (PWM)-controlled GTO converter circuit is proposed. An auxiliary circuit capacitor is used to treat the commutating energy in the main circuit and to clamp the commutating impulse voltage at the desired level with the fundamental power factor of unity. An analysis of the circuit operation is verified experimentally.
