MULTIRESONANT SELF-OSCILLATING CONVERTER CIRCUIT

摘要

A direct current to direct current converter utilizes a MOSFET half-bridge configuration in which the inherent magnetizing and leakage inductances of the transformer (10) are used as the only inductances in the frequency-determining circuit. Diodes (30, 31) are used to limit the voltages across the capacitor (23) of the frequency-determining circuit and hence limit the short circuit and open circuit characteristics of the converter. A self-starting circuit (35) insures that the circuit will start up when initially energized.
