Abstract:
A combined voltage regulator and snubber circuit generally has a voltage regulator device in parallel with the energy storage element of the snubber circuit operatively connectable in series with a leakage inductance current path; the leakage inductance being part of a magnetic component utilized in a switch-mode power supply having an input voltage source, controllable semiconductor switches, freewheeling semiconductor switches, feedback controller, reactive energy storage components and a load; the voltage regulator generally providing constant or variable voltage to the gate driver of the controllable semiconductor and/or feedback controller.

Claim (Index 1):
A switch-mode power supply comprising:\n a transformer having at least one primary winding, an auxiliary winding, and a load output; a converter cell, the converter cell comprising:\n an input capacitor connected to a primary winding of the at least one primary windings at a first node, \n a snubber circuit comprising an energy storage device and a reverse-biased diode connected in series with the energy storage device, the primary winding connected in parallel with the snubber circuit by the first node and a second node, \n a switch driven by a gate driver and controlling a current through the primary winding, and \n a voltage regulator having an input and a regulated output, the regulated output of the voltage regulator connected to voltage rails of the gate driver, the input of the voltage regulator connected in parallel across the input capacitor; and \n a low-dropout regulator; wherein the auxiliary winding provides an auxiliary voltage to the low-dropout regulator for providing power to the input capacitor.
