ABSTRACT:
A series resonant circuit is coupled to a direct voltage source via two push-pull connected thyristors and diodes connected inverse-parallel there across. A zero-crossing detector generates a zero-crossing signal as soon as the thyristor ignition pulse current through the series resonant circuit drops below a given value after its zero crossing, and an ignition pulse generator which is controlled by the zero-crossing detector generates ignition pulses for the thyristors. To prevent unintended interruption of the inverter operation, a measuring device measures the time interval between an ignition pulse and the subsequent zero-crossing signal, a memory stores the time interval for normal operation, and a circuit generates an auxiliary zero-crossing signal when the measured time interval exceeds the stored time interval by more than a predetermined value.
