Abstract
An inverting circuit of the series resonant type and including a pair of SCR's operated at variable off-times for controlling the charging of a battery. A control circuit is provided for gating the SCR's at appropriate times in response to sensed circuit current, and battery voltage. Instantaneous resonant circuit current is monitored to derive timing information for firing the SCR's and for anticipating commutation failures.
