Problems solved by technology

In recent years, more and more electrical equipment is used in the car, so that there are many wire harnesses wrapped around the center console of the car, and the interior of the car will appear messy
In addition, when the mobile phone is charging, it is very inconvenient to answer the call due to the connection of the wire harness. The circuits used in the existing chargers are generally more complicated, and a large amount of heat is often generated during the charging process, which makes the charging process difficult. device poses a safety hazard

Abstract

The invention discloses a charger circuit, and particularly discloses a vehicle-mounted charger circuit. The vehicle-mounted charger circuit comprises a transformer (B), an integration three-end voltage stabilizing block LM317, a rectifier bridge (L), resistors (R1, R2, R3, R4, R5, R6, R7, R8, R9), light emitting diodes (LED1, LED2, LED3, LED4), a variable resistor (RV), storage batteries (EV1, EV2, EV3, EV4) and triodes (BG1, BG2, BG3, BG4), and is characterized in that the vehicle-mounted charger circuit is a multi-output full-bridge conversion circuit.

Description

【Technical field】 [0001] The invention relates to charger equipment, in particular to a vehicle charger circuit. 【Background technique】 [0002] At present, with continuous breakthroughs in microelectronics technology, automotive electronics technology has also entered a new era. Cars are no longer a simple driving tool, but a comprehensive product integrating entertainment, comfort and multi-purpose. In recent years, however, more and more electrical equipment is used in automobiles, causing multiple wire harnesses to be entangled at the center console of the automobile, and the interior of the automobile will appear messy. In addition, when the mobile phone is charging, it is very inconvenient to answer the call due to the connection of the wire harness. The circuits used in the existing chargers are generally more complicated, and a large amount of heat is often generated during the charging process, which makes the charging process difficult. device poses a safety hazar...
