Abstract
A resonant power converter includes a resonant capacitor, a transformer, a high-side transistor, a low-side transistor, a divider, a full-wave rectification device, a control circuit, and a rectifying circuit. The resonant capacitor is coupled between a resonant node and a ground. The transformer includes a primary coil coupled between a switch node and the resonant node and a secondary coil. The high-side transistor provides an input voltage to the switch node and the low-side transistor couples the switch node to the ground. The divider divides a voltage of the resonant node to generate a divided signal. The full-wave rectification device full-wave rectifies the divided signal to generate a full-wave rectified signal. The control circuit compares the full-wave rectified signal to a feedback voltage related to an output voltage to drive the high-side transistor and the low-side transistor. The rectifying circuit generates the output voltage.
