Power line introduction of 220V mains, fuse overcurrent protection, filter filter clutter interference, rectifier bridge AC into DC, filter capacitor to make DC more stable, IC3842 current and voltage management and generate oscillation control signal, start resistance supply oscillation chip power supply, LY431 provides 2.5V standard voltage, photoelectric coupler to adjust the switching tube current, High-voltage transformers turn direct current into alternating current, Schottky diodes for high-frequency current rectification, electrolytic capacitors for low-voltage direct current filtering, fans for power tube rectifier cooling, indicator lights indicate working status. The DC output plug is connected to the battery for charging.
The main components used in electric vehicle chargers are: resistance, capacitor, diode triode field effect tube integrated circuit resistance is the main physical characteristics of the power conversion for heat energy, it can also be said that it is an energy-consuming component, the current through it to produce internal energy.
Resistance in the circuit usually plays the role of voltage division, for the signal, AC and DC signals can pass through the resistance. (Greek letters, transliterated into pinyin pronounced as pomu mi g, C) applied to limited flow...
