摘要： A light source driving device includes a power factor correction (PFC) circuit, a power stage circuit, a power conversion circuit, a balancing circuit, an inverter control signal processor, an inverter controller and an isolation component. Alternating current (AC) signals are converted into electrical signals to drive lamps via the PFC circuit, the power stage circuit, the power conversion circuit and the current balancing circuit. The power conversion circuit including a transformer divides the driving device into a primary side and a secondary side. The inverter control signal processor receives a first control signal output from a secondary side and generates a second control signal. The inverter controller is disposed on the secondary side to drive the power stage circuit.The isolation component transmits the second control signal to the inverter controller and isolates the inverter control signal processor from the inverter controller.
