A power supply circuit for providing a positive, intermediate, and negative voltage supply includes positive and negative DC voltage buses that connect to a power source; a first voltage divider that is connected between the positive and the negative DC voltage buses, that includes a first transistor connected to the negative DC voltage bus, and that provides the intermediate voltage supply; a second voltage divider that is connected between the positive and the negative DC voltage buses and that is connected to the first transistor; and a short circuit protection module that includes a second transistor connected between outputs of the first and second voltage dividers and connected to the first transistor and that includes a current limiting element connected to the first transistor and configured to limit power dissipated by the first transistor in the case of a short circuit to the intermediate voltage supply.
A three output DC voltage supply with short circuit protection for providing a positive, intermediate, and negative voltage supply, comprising:
