Simulation of Low Voltage Electrical System of Tram

Automotive electrical equipment can be summarized into three major components: power supply system, electrical equipment, and intermediate devices. For any electrical equipment and electronic control device to obtain power supply, the connection of intermediate devices is essential. The generator is the main power source of the car, and its function is to supply power to all electrical equipment (except the starter) when the engine is running normally (above idle speed), and to charge the battery at the same time. In this paper, by modeling the circuit of low-voltage electrical system of trams and designing and realizing the circuit model of low-voltage electrical system, this article masters the basic knowledge of circuit analysis, is familiar with the general process of circuit design, and can solve the general circuit faults in debugging.
