- Abstract
- A constant frequency control of an LLC resonant converter is presented. A switched capacitor is introduced to change the resonant capacitance, which enables the control of the voltage gain at a fixed switching frequency. The operation principle of the proposed converter with a switched capacitor is discussed. The experimental results are provided to show the validity of the proposed method.
