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.

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, wherein the system is configured to run in a static mode, wherein when in the static mode the electronic processor is configured to activate an electrical characteristic boost when the system is initially powered by a shore power supply.
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;
- operating in a static mode, wherein when in the static mode the isolation transformer boost system is configured to activate an electrical characteristic boost when the system is initially powered by a shore power supply.
