Abstract
A strobe light power source includes a capacitor which is alternately charged through an inverter transformer and a rectifier and discharged through a strobe lamp. A MOSFET switch is connected in series with the transformer primary and has applied to its gate electrode a rectangular wave output signal from an oscillator. The oscillator and the transformer primary are coupled to a power supply independently of each other. A breakdown diode is connected in parallel with the MOSFET to limit the voltage thereacross.
