Charging units into Charger consists of five major components: EMC / EMI EMC filters, rectifiers, PFC power factor correction, DC-DC isolation transformer; MCU charge controller. 1 EMC filter; mainly filter for EMC / EMI interference to prevent interference or interference caused by incompatibility issues. Two rectifier; Yes AC to DC conversion device. 3.PFC power factor correction; In order to reduce harmonic interference generated by nonlinear rectifier unit, nonlinear rectifying device must be installed power factor correction circuit. 4.DC-DC isolation transformer; due to strong grid voltage, direct charging will lead to security problems, in order to comply with safety regulations require isolation. 5.MCU charge controller; charging process monitoring and control to ensure the battery charging automatically. 2.2.
