Abstract:
A self oscillating converter with regenerative switching includes circuitry to enhance the gain of circuity to turn off a MOSFET power switch and enhance the regenerative action culminating in turn off in order to eliminate bursting at low loads. The MOSFET power switching device turn off circuitry includes the addition of a supplementary drive transistor operative for counteracting the effects of the parasitic capacitances of the MOSFET power switching device. This permits the converter to operate with the shorter on times and to provide a low ripple output at very low load.
