Abstract

An isolation transformer boost system. The system includes a power supply and an isolation transformer. The isolation transformer includes a primary winding electrically connected to the power supply, a secondary winding, a first voltage tap, and a second voltage tap. Wherein the isolation transformer is configured to, in response to a command from an electronic processor, disconnect a connection from the second voltage tap and establish a second connection from the first voltage tap, wherein the command is based on an electrical characteristic measurement of the power supply exceeding an upper limit threshold for a predetermined period of time.

First claim

What is claimed is:

1 . An isolation transformer boost system, the system comprising:
a power supply; and an isolation transformer including
a primary winding electrically connected to the power supply,
a secondary winding,
a first voltage tap, and
a second voltage tap;
wherein the isolation transformer is configured to, in response to a command from an electronic processor, disconnect a connection from the second voltage tap and establish a second connection from the first voltage tap, wherein the command is based on an electrical characteristic measurement of the power supply exceeding an upper limit threshold for a predetermined period of time.

2 . The isolation transformer system of claim 1 , wherein the first voltage tap and the second voltage tap are electrically connected between the secondary winding and an output.

3 . The isolation transformer system of claim 1 , wherein the first voltage tap and the second voltage tap are electrically connected between the primary winding and the power supply.

4 . The isolation transformer of claim 1 , wherein the upper limit threshold is at least one selected from a group consisting of 190 V, 195 V, 200 V, 205 V, 210 V, 215 V, and 220 V.

5 . The isolation transformer of claim 1 , wherein the isolation transformer is further configured to, in response to a second command from the electronic processor, disconnect the second connection between the first voltage tap and the power supply.

6 . The isolation transformer of claim 5 , wherein the second command is based on an electrical characteristic measurement of the power supply being less than a predetermined threshold.

7 . The isolation transformer of claim 6 , wherein the predetermined threshold is at least one selected from a group consisting of 190 V, 195 V, 200 V, 205 V, 210 V, 215 V, and 220 V.

8 . A method of operating an isolation transformer boost system including a power supply and an isolation transformer, wherein the isolation transformer includes a primary winding electrically connected to the power supply, a secondary winding, a first voltage tap, and a second voltage tap, the method comprising:
measure, via a sensor, an electrical characteristic of the power supply; determine, via an electronic processor, when the electrical characteristic exceeds an upper limit threshold for a predetermined period of time; in response to determining the electrical characteristic has exceeded the upper limit threshold for the predetermined period of time, output, via the electronic processor, a command to the isolation transformer; and in response to receiving the command, disconnect a connection from the second voltage tap and establish a second connection from the first voltage tap.

9 . The method of claim 8 , wherein the first voltage tap and the second voltage tap are electrically connected between the secondary winding and an output.

10 . The method of claim 8 , wherein the first voltage tap and the second voltage tap are electrically connected between the primary winding and the power supply.

11 . The method of claim 8 , wherein the upper limit threshold is at least one selected from the group consisting of 190 V, 195 V, 200 V, 205 V, 210 V, 215 V, and 220 V.

12 . The method of claim 8 , further comprising, in response to receiving a second command from the electronic processor, disconnect the second connection between the first voltage tap and the power supply.

13 . The method of claim 12 , wherein the second command is based on an electrical characteristic measurement of the power supply being less than a predetermined threshold.

14 . The method of claim 13 , wherein the predetermined threshold is at least one selected from the group consisting of 190 V, 195 V, 200 V, 205 V, 210 V, 215 V, and 220 V.
