The difference between DC motorcycle and AC motorcycle

There are two kinds of power supply for ordinary motorcycle headlights, AC and DC. I'll tell you a simple identification method. Generally, the headlights of motorcycles started with electricity are powered by DC, while those started without electricity are mostly powered by AC, while those started with electricity are powered by AC. This kind of car is easy to identify. See if the headlights of the car can be turned on after the key is turned on. If not, it is powered by AC and DC, the brightness of the headlights of AC-powered vehicles varies with idle speed.

Alternating current is not easy to save, and direct current can be obtained from the battery or alternating current rectification, so it is more suitable for some places where alternating current is inconvenient to apply. For example, hand-held tools, mobile bicycles, trams, etc., use direct current. The advantage of alternating current over direct current is that the sustainable power supply is large, after all, the battery is also large. The equipment in the car can only work through direct current, and alternating current cannot make the car run, because most of the equipment in the car is a circuit board, and some components, such as transistors and most integrated chips, are DC power supply., They must have their own static working state, which is the DC working state. Most transistors can play their functions in the DC environment. Integrated amplifier circuits used in electronic circuits, operational amplifier circuits, logic circuits and many other circuits use transistors as electronic components. It is important that the transistor has two operating points in the circuit, one is a static operating point and the other is a dynamic operating point. The static operating point can affect the dynamic operating point and may directly affect the performance of the integrated circuit. Whether the amplified signal is distorted or not. Therefore, the setting of the static working point is very important, and the static working point is working in the DC state, so the circuit board power supply is DC.
