Television power supply driving device and television

A television power supply driving device, comprising a power board connected to a mainboard and a backlight module, the power board has a PFC circuit arranged, wherein the power board has further arranged an auxiliary power supply for supplying power to the mainboard, and a main power supply for supplying the backlight module;

• the auxiliary power supply comprises a first LLC resonance module, a resonance control module, a standby control module, a power supply module, and a rectifying filter module;
• the main power supply comprises a second LLC resonance module, a secondary LLC control module, and a synchronous rectifier module;
• after powered on, when receiving a power-on signal, the standby control module controls the power supply module to turn on the resonance control module and the PFC circuit successively, the PFC circuit outputs a PFC voltage to the first LLC resonance module and the second LLC resonance module, the first LLC resonance module converts the PFC voltage into a first voltage and a second voltage according to a first control signal output from the resonance control module, the first voltage and the second voltage are then output to the mainboard and the secondary LLC control module for power respectively, after being rectified and filtered by the rectifying filter module;
• the second LLC resonance module converts the PFC voltage into a third voltage according to a second control signal output by the secondary LLC control module, and the third voltage is output to the backlight module for power after being synchronous rectified by the synchronous rectifier module;
• the standby control module controls the power supply module to shut down the PFC circuit to stop outputting the PFC voltage, when receiving a standby signal, making the resonance control module enter a standby state.
