Abstract
The configurations of a compensation device configured in a circuit having a synchronous rectifier (SR), a controller and a load, and a compensation method thereof are provided in the present invention. In the proposed circuit, the SR includes a first terminal, a first inductor electrically connected to the first terminal in series, a second terminal and a second inductor electrically connected to the second terminal in series, the controller is coupled to the first and the second inductors, and the device includes a voltage source having a positive terminal coupled to the controller and a negative terminal coupled to the second inductor and providing a compensation voltage to reduce or eliminate the influence of the first and the second inductors towards a voltage value across the first and the second terminals.
