DC-to-DC converter with variable set-point control

摘要

A DC-to-DC converter may be disposed in a vehicle for converting a high voltage from a power source to a low voltage. The DC-to-DC converter may include a primary converter, a secondary converter, and a DC-to-DC module. The DC-to-DC module may control the operation of the secondary converter based on a set-point threshold and a power output of the primary converter, where the set-point threshold may be variably set.

主权项

1. A DC-to-DC converter for a vehicle, the DC-to-DC converter comprising:
a primary converter electrically coupled to a power source of the vehicle, the primary converter converting a first voltage from the power source to a second voltage lower than the first voltage; a secondary converter electrically coupled to the power source, the secondary converter converting the first voltage from the power source to the second voltage; and a DC-to-DC module controlling the secondary converter based on a set-point threshold and a power output of the primary converter, wherein the set-point threshold is variably set, and the DC-to-DC module activates the secondary converter when the power output of the primary converter is greater than or equal to the set-point threshold and deactivates the secondary converter when the power output of the primary converter is less than the set-point threshold.
