ABSTRACT:
An improved energy conversion apparatus for use in charging energy storage capacitors for energizing flash lamp devices. A transformer has a primary winding coupled to a low voltage DC source and transistor switches and a secondary winding coupled to a chargeable capacitor. The transistor switches are turned on or off in response to current signals in the primary and secondary windings. A detection circuit senses the energy stored in the capacitor and supplies signals to the transistor switches to maintain energy stored in the capacitor at a predetermined level.
