Description

Technical field [0001] The intelligent negative pulse repair charger of the present invention relates to a switching power supply technology, using a semiconductor power device as a switch to convert the mains power into the voltage and current required for battery charging. As the capacity and stored electric energy of the battery are different, the required voltage and current are different at different charging stages. The intelligent negative pulse repair charger uses a single-chip microcomputer to accurately sample, and uses pulse width modulation (PWM) to control the opening of the electronic switch. It can control the output of switching power supply and realize closed-loop control. Background technique [0002] At present, a large number of popular three-stage chargers on the market divide the charging process into three stages: constant current, constant voltage, and floating charge. Take the 36V12Ah lead-acid battery pack that is used in my country's electric vehicle in...
