Publication number: 20240128876Abstract: A switching control circuit for use in controlling a resonant flyback power converter generates a first driving signal and a second driving signal. The first driving signal is configured to turn on the first transistor to generate a first current to magnetize a transformer and charge a resonant capacitor. The transformer and charge a resonant capacitor are connected in series. The second driving signal is configured to turn on the second transistor to generate a second current to discharge the resonant capacitor. During a power-on period of the resonant flyback power converter, the second driving signal includes a plurality of short-pulses configured to turn on the second transistor for discharging the resonant capacitor. A pulse-width of the short-pulses of the second driving signal is short to an extent that the second current does not exceed a current limit threshold.Type: ApplicationFiled: June 15, 2023Publication date: April 18, 2024Inventors: Yu-Chang Chen, Ta-Yung Yang, Kun-Yu Lin, Fu-Ciao Syu, Chia-Hsien Yang, Hsin-Yi Wu
