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.

    本发明提供了一种基于车载等离子体驱动电源的输入输出供电系统,属于车载供电技术领域,包括启动电路、辅助供电电路和主功率电路。当输入供电,经过启动电路给芯片稳定供电,芯片产生PWM驱动信号,主功率电路MOS管开始工作,变压器给输出提供稳定电压,输出绕组经变压器耦合到辅助供电绕组,通过变压器辅助绕组供电电路给芯片提供稳定供电电压,启动电路部分停止工作,减少电路功率损耗。本发明的供电电路输入电压宽范围、输出电压宽范围,从而控制芯片供电电压稳定,不会因输入输出电压波动导致芯片供电不足或损坏,从而影响产品可靠稳定运行。
