Patent ID: 11115618

Abstract:
The present disclosure discloses television power driving device and television, standby control module controls power supply module to turn on resonance control module and PFC circuit successively when receiving power-on signal, PFC circuit outputs PFC voltage to first and second LLC resonance modules, first LLC resonance module converts PFC voltage into first voltage and second voltage according to first control signal, outputs respectively to mainboard and secondary LLC control module for power, after being rectified and filtered by rectifying filter module. Second LLC resonance module converts PFC voltage to third voltage according to second control signal, outputs to backlight module for power after synchronous rectified by synchronous rectifier module; standby control module controls power supply module to shut down PFC circuit to stop outputting PFC voltage, when receiving standby signal, making resonance control module enter standby state, simplifying power supply architecture and avoiding limiting power efficiency or heat dissipation.
