Abstract:
A multipurpose power supply suitable for a power switch driver circuit takes an input voltage and generates output voltages at four output terminals. Two output terminals may be connected to voltage supply rails to drive a switched-mode power converter. The voltage output at each output terminal relative to ground is different, allowing the voltage rails to be set to voltages suitable for a variety of different power-switch driver circuits by adjusting the output terminals to which the voltage rails are connected. A reference voltage is applied to one output terminal in order to set the values of the voltages at the remaining output terminals.

Claim (Index 9):
A system comprising:\n a power electronics device including one or more transistors of the same type and high and low input power rails that provide the one or more transistors with power, the transistor type being MOSFET, SIC, or IGBT; a power switch driver power supply circuit that provides power to the power electronics device, comprising:\n a pair of input terminals that receive input power; \n four output terminals that output power to the power electronics device, wherein when an input voltage is applied across the input terminals, each of the four output terminals is held at a substantially different voltage relative to ground such that a first voltage difference exists between the first and second output terminals, a second voltage difference exists between the second and third output terminals, and a third voltage difference exists between the third and fourth output terminals; wherein \n one of the four output terminals is connected to a reference voltage to set the values of the respective voltages at which the four output terminals are each held relative to ground; two of the remaining three output terminals are connected to the high and low input power rails of the power electronics device to provide an input voltage difference across the two of the remaining three output terminals; and the selection of the three output terminals to be connected to the reference voltage and the high and low input power rails of the power electronics device from among the four output terminals selects different combinations of the first, second, and third voltage differences to change the input voltage difference provided across the high and low input power rails according to whether the transistor type is MOSFET, SIC, or IGBT.
