ADJUSTABLE THREE OUTPUT DC VOLTAGE SUPPLY WITH SHORT CIRCUIT PROTECTION: abstract simplified (18210793)

• This abstract for appeared for patent application number 18210793 Titled 'ADJUSTABLE THREE OUTPUT DC VOLTAGE SUPPLY WITH SHORT CIRCUIT PROTECTION'

Simplified Explanation

The abstract describes a circuit that can provide three different DC voltages. It has positive and negative voltage buses that connect to a power source. There is a voltage divider connected between the positive and negative buses, which includes a shunt regulator that provides an intermediate voltage. Another voltage divider is connected between the positive or negative bus and the intermediate voltage, and it has an output connected to a reference input of the shunt regulator. There is also a short circuit protection component that limits the current through the shunt regulator if there is a short circuit to the intermediate voltage.

Original Abstract Submitted

An adjustable three output DC voltage supply circuit includes positive and negative DC voltage buses that connect to a DC power source; a first voltage divider connected between the positive and negative DC voltage buses and including a shunt regulator that is connected to the positive DC voltage bus and that provides an intermediate voltage supply; a second voltage divider connected between the positive or the negative DC voltage bus and the intermediate voltage supply and including an output that is connected to a reference input of the shunt regulator; and a short circuit protection component connected in series to a low voltage side of the shunt regulator and configured to limit the current through the shunt regulator in the case of a short circuit to the intermediate voltage supply.
