Description of product use effect
220V AC is suppressed by T0 bidirectional filter, D1 rectifier is pulsating DC, and then C11 filter is used to form stable 300V
DC. U1 is a TL3842 pulse width modulation integrated circuit. Its five legs are negative poles, seven legs are positive poles, six
legs are pulse output direct drive field effect transistor Q1 (K1358) and three legs are maximum current limit. Adjusting the
resistance of R25 (2.5 ohms) can adjust the maximum current of charger. Principle Diagram of Charger for Electric Vehicle Electric
vehicle charger schematic diagram (2) Two feet are voltage feedback, which can adjust the output voltage of the charger. Four pins
external oscillating resistance R1 and oscillating capacitor C1. T1 is a high frequency pulse transformer with three functions.
