  • Emergency power source
    Patent number: 4311920
    Abstract: An emergency power supply designed to furnish sinusoidally varying alternating current to a load under emergency conditions is disclosed. It features a fixed phase shift between input and battery charging waveforms, and intermittent inverter operation under normal (i.e., non-emergency ) conditions.

  • Series resonant battery charger and control therefor
    Patent number: 4200830
    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.
