Abstract : The patent describes a micro-miniaturized high efficiency power supply using the principle of open loop voltage regulation. The circuit employs full-wave rectification at the input followed by filtering, pre-regulation, inverter isolation and final saturated series regulation with noise suppression and energy storage filters at appropriate strategic places. A hold up circuit initially supplies power to control circuitry. When a pre-regulator attains a predetermined value the hold up circuit is turned off and a pre-regulator then supplies power to the control circuitry.
