Electric car charger principle, the charger control chip is generally based on the TL494 as the core, to promote the 2 13007 high voltage triode. In combination with LM324 (4 operational amplifier), the three stage charging is realized. 220V AC rectifier through D1-D4, C5 filter to get about 300V direct current. This voltage charges the C4 and initiates the current through the TF1 high voltage winding, the TF2 main winding, and the V2. The TF2 feedback winding generates an induced voltage that turns the V1 and V2 in turn. Therefore, the low-voltage power supply winding in TF1 generates voltage...
