Abstract:
In an example, a controller device for a resonant converter includes processing circuitry configured to output a first switching signal and a second switching signal. A switching module is configured to electrically couple a primary side winding of a transformer to a voltage source during an activated state of the first switching signal and to electrically couple the primary side winding to a reference node during an activated state of the second switching signal. The processing circuitry is further configured to determine a first synchronous rectification signal and a second synchronous rectification signal. A synchronous rectification module is configured to generate a first channel for a first secondary side winding of the transformer during an activated state of the first synchronous rectification signal and to generate a second channel for a second secondary side winding of the transformer during an activated state of the second synchronous rectification signal.
