  • Overcurrent protection circuit for a multiple output switching power supply and method therefor
    Patent number: 4447841
    Abstract: An overcurrent protection circuit and method therefor for use in a multiple output switched power supply wherein the overcurrent condition accompanying a short circuit or an overload in an output circuit is detected as an undervoltage in a transformer. When the undervoltage exceeds a threshold the power supply is switched off and then on again during the cycling of a low frequency oscillator until the short or overload is removed in order to maintain the average power through the output circuit at a safe level.
