Abstract
A power regulation device is connected between a power source and a load for receiving receive first voltage from the power source and providing a second voltage to the load. The power regulation device includes a first voltage detection circuit for detecting the first voltage and a second voltage detection circuit for detecting second voltage. A controller receives signals representing the first and second voltages and compares the signals with preset references to issue control signals. A switch circuit is connected between the power source and the load and is coupled to and controlled by the controller. The switch circuit is controlled by the control signals of the controller to change from the first state to a second state for selectively passing the first voltage and inducing different levels of the second voltage which are associated with different powers supplied to the load.
