Abstract
A resonant rectifying device includes a transformer having a primary winding and a secondary winding, a primary-side circuit coupled to the primary winding of the transformer, and a secondary-side circuit coupled to the secondary winding of the transformer. The primary-side circuit includes a first field effect transistor (FET) and a second FET coupled in series between a voltage source and a ground, a capacitor, and an inductor. A first side of the capacitor is coupled to a point between the first and the second FETs. A second side of the capacitor is coupled to a first end of the inductor and one end of the primary winding. A second end of the inductor is coupled to the ground. The secondary-side circuit includes a third FET and a fourth FET coupled to a first end and a second end of the secondary winding, respectively.
