PURPOSE: A sample charging control method for a resonant converter is provided to improve a response property of a converter by decreasing an output voltage overshoot and an input current overshoot of an LLC resonant converter. CONSTITUTION: A first switch(103) and a second switch(104) provide AC waveform to a primary winding of a transformer(105). A resonant circuit includes a magnetization inductor(106), a resonant inductor(107), and a resonant capacitor(108). A rectification circuit(110) includes a rectification diode(111a-111d) and an output capacitor(112) which is connected to a secondary winding of the transformer. A VCO(Voltage-Controlled Oscillator)(113) provides a first pulse train with a first frequency. A frequency divider provides a second pulse train to an output terminal(102). |
