ABSTRACT:
This disclosure is of an inverter type power supply including an actively switched damping circuit for limiting voltage transients in the inverter circuitry. Such damping is accomplished by switching an energy absorbing element into parallel circuit relationship with the inverter transformer during periods in which transients normally occur, the energy absorbed during these transients then being either dissipated or stored and later returned to the inverter transformer for improved circuit efficiency.
