Abstract

A power supply for IGBT/FET drivers (1) that provides separated, isolated power to each IGBT/FET driver in a system wherein the power supply (1) is connected to at least one voltage controller (16) having at least one line in main power connector (14), at least one line out main power connector (15) and at least one drive signal command input (11) for connection to at least one IGBT/FET driver. The power supply (1) includes at least one power supply unit (5) in connection with at least voltage controller (16), at least one diode (2) for routing a predetermined amount of power from the at least one voltage controller (16) to at least one capacitor (3) and at least one capacitor (3) for routing said predetermined amount of power from said at least one diode (2) to said at least one voltage controller (16).
