ABSTRACT:
A series resonant circuit and at least two push-pull connected electronic switches are traversed by a respective halfwave of the resonant-circuit current and via which switches the series resonant circuit is coupled to a d.c. source. GTO thyristors form the electronic switches, which thyristors are switched by a pulse generator device which generates a blocking pulse at the zero crossing of the resonant-circuit current and which generates a trigger pulse for the subsequently conductive GTO thyristor a predetermined delay time after activation of the blocking pulse to selectively shape the output current of the inverter to control the resultant power.
