A self-excited oscillator type switch power supply equipment with overcurrent protection. For adopting simple and reliable negative current feed back protective circuit with complementary bridged circuit, positive feed back circuit without direct current biasing capacitive coupling, initial-oscillation circuit of an alternative current power supply etc. The self-excited oscillator type switch power supply is made a practical power supply equipment with simple circuit, small volume and low cost.
