摘要
The DC-to-DC converter including a boost converter circuit, a resonant circuit, and an active power sink circuit is provided. The boost converter circuit has a main switch for boosting a first DC voltage into a second DC voltage. The resonant circuit includes a unidirectional switch, a resonant capacitor, and a first winding of a transformer for causing the main switch to be controlled to exhibit near zero voltage switching. And, the active power sink circuit is magnetically coupled to the first winding of the transformer for draining energy in an inductance of the transformer off via magnetic induction between the active power sink circuit and the transformer, and causing the unidirectional switch to be controlled to exhibit near zero current switching.
