  • Power supply module having internal energy storage circuit for stable oscillation
    Patent number: 6548993
    Abstract: A power supply module has an internal energy storage circuit to reduce the number of external wire connections to the power supply module. The power supply module is used to provide pulsed electrical energy to a load. The power supply module includes a semiconductor switch, an oscillator, and an energy storage circuit. The energy storage circuit accumulates energy for providing electrical energy to the oscillator to maintain stable, active operation of the oscillator and to provide a control voltage for the semiconductor switch.
