ABSTRACT:
A self oscillating power converter utilizing a pair of MOSFET transistor switches in a half bridge configuration wherein the junction of the two transistors is coupled to a reactive network which in turn is connected to an output rectifier. The gate-to-drain inter-electrode capacitance of the switching transistors serves as the sole means of sustaining oscillations. Oscillations are started at the gate-to-source electrodes of the transistors by a startup circuit. The frequency of oscillation is determined by the gate-to-source capacitance of the transistors and the inductance of the drive transformer which couples the source-to-gate electrodes of the transistors to each other. The drive transformer is provided with a means of varying its inductance thereby changing the switching frequency so as to regulate the voltage.
