Abstract

The invention relates to a high-power charging circuit and apparatus. The circuit comprises a control circuit, an inlet wire isolation circuit, a voltage regulation and charging circuit, and an output isolation circuit. The control circuit is connected with the inlet wire isolation circuit, the voltage regulation and charging circuit, and the output isolation circuit; and the inlet wire isolation circuit, the voltage regulation and charging circuit, and the output isolation circuit are connected successively in series. According to the circuit and apparatus, various constant-current, constant-voltage, and constant-power charging modes are provided; automatic adjustment can be carried out based on a practical state of to-be-charged equipment; and over-voltage over-current, over-temperature, and under-voltage protection is provided for the to-be-charged equipment. Therefore, rapid and safe charging of the to-be-charged equipment is realized.

Description

technical field [0001] The invention relates to the technical field of charging, in particular to a high-power charging circuit and device. Background technique [0002] The traditional power supply method of domestic trams adopts the catenary power supply, and the catenary is responsible for the important task of directly transmitting the electric energy obtained from the traction substation to the trams, so the quality and working status of the catenary will directly affect the operation of trams. In addition, the braking system of conventional trams dissipates braking energy in the form of heat. [0003] Due to the innovative design of energy storage, the new modern tram has neither exhaust pollution nor overhead power grid operation. The biggest feature of this tram is that it uses a supercapacitor as the traction power supply, and there is no need to erect aerial cables "spider webs" ", can be laid directly on existing roads, mixed with other public transportation, wi...
