Abstract
The proposed soft-switching DC/DC converter includes a converter circuit including a main switch having a first, a second and a control terminals for converting an input DC voltage to an output DC voltage, a resonant circuit electrically connected to the converter circuit, and an energy transferring circuit including an auxiliary switch having a first, a second and a control terminals and magnetically coupled to the resonant circuit. In which, the main switch is turned on under a specific voltage across the first and the second terminals of the main switch and the auxiliary switch is turned off under a specific current flowing through the first and the second terminals of the auxiliary switch both controlled by the resonant circuit through a resonance effect so as to accomplish a soft-switching of the converter.
