Description

technical field [0001] The invention relates to a power supply control circuit of a solar rechargeable automatic dimming filter mirror. Background technique [0002] During welding, in order to avoid welding spatter and arc damage to welding operators, general welding operators need to wear welding masks. Ordinary automatic dimming masks are composed of masks and automatic dimming filters. Conventional automatic dimming filters The filter is generally powered by a button battery, and the button battery has a small power, which is not enough to support the long-term work of the high-power circuit. After improvement, a solar rechargeable automatic dimming filter is designed, which uses solar panels to charge the supercapacitor. Since the welding working time is much shorter than the standby time, the solar battery and supercapacitor basically meet the requirements of automatic dimming. Power requirements for the dimming filter. It can reduce the cost of battery replacement f...
