Abstract

The invention discloses a transformer and a manufacturing method of a transformer. The transformer is placed in a groove made of a metal shell, and the metal shell is grounded; the transformer comprises a voltage transformation circuit and a rectification circuit; the input end of the voltage transformation circuit is connected with a power supply, the first output end of the voltage transformation circuit is connected with the input end of the rectification circuit, and the second output end of the voltage transformation circuit is electrically connected with the metal shell; the voltage transformation circuit is used for transmitting the output current of the power supply to the rectification circuit; the first output end of the rectification circuit is connected with a low-voltage battery, and the second output end of the rectification circuit is electrically connected with the metal shell; and the rectification circuit is used for rectifying and filtering the output current of thevoltage transformation circuit so as to transmit the output current to the low-voltage battery for charging through the first output end of the rectification circuit. By implementing the embodiment ofthe invention, the complexity of the circuit is reduced.

Description

technical field [0001] The present application relates to the technical field of electric vehicle charging, and in particular, to a transformer and a method for manufacturing the transformer. Background technique [0002] Generally speaking, the on-board power battery is charged by the on-board charger. During power transmission, it is often necessary to isolate and transmit energy through a transformer. [0003] In the prior art, the coil of the transformer is usually mounted on the pins of the transformer skeleton with flying leads or copper wires, and then soldered to the circuit board to form a current loop and achieve the purpose of transmitting power. This way the circuit design is complicated. SUMMARY OF THE INVENTION [0004] The embodiments of the present application provide a transformer and a method for manufacturing the transformer. By implementing the embodiments of the present application, the circuit complexity is reduced. [0005] A first aspect of the em...
