The invention provides an input and output power supply system based on a vehicle-mounted plasma driving power supply, which belongs to the technical field of vehicle-mounted power supply. The system comprises a starting circuit, an auxiliary power supply circuit and a main power circuit. During input power supply, power is stably supplied to a chip through a starting circuit, the chip generates a PWM driving signal, a main power circuit MOS tube starts to work, a transformer provides a stable voltage for output, an output winding is coupled to an auxiliary power supply winding through the transformer, an auxiliary winding power supply circuit provides a stable power supply voltage for the chip through the transformer, and the starting circuit part stops working. And a circuit power loss is reduced. The power supply circuit has a wide input voltage range and a wide output voltage range so that the power supply voltage of a chip is controlled to be stable, and reliable and stable operation of a product is not influenced by insufficient power supply or damage of the chip caused by fluctuation of the input and output voltages.
