THREE OUTPUT DC VOLTAGE SUPPLY WITH SHORT CIRCUIT PROTECTION - A simplified explanation of the abstract

  • This abstract for appeared for US patent application number 18210820 Titled 'THREE OUTPUT DC VOLTAGE SUPPLY WITH SHORT CIRCUIT PROTECTION'

Simplified Explanation

The abstract describes a power supply circuit that provides three different voltage supplies: positive, intermediate, and negative. It consists of positive and negative DC voltage buses connected to a power source. The circuit includes two voltage dividers connected between the positive and negative buses. The first voltage divider, which includes a transistor, generates the intermediate voltage supply. The second voltage divider is connected to the first transistor. Additionally, there is a short circuit protection module that includes a second transistor connected between the outputs of the voltage dividers. This module also includes a current limiting element connected to the first transistor, which helps limit power dissipation in case of a short circuit to the intermediate voltage supply.


Original Abstract Submitted

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.
