MOTORCYCLE ELECTRICAL COMPONENT: DIODE

Diode is a component that is mounted on a motor cycle on a unit that functions as a rectifier circuit electric current, please refer to the complete information.

 

Figure 1. Diodes and symbols

A diode is defined as an alloy of two electrodes, one being positive (anode) and the other is negative (cathode) and only allow current to flow in one direction. Diode is a semiconductor component that serves to allow current to flow in a circuit dalarn only one direction (forward bias), ie from the anode to the cathode and block the current flowing in the opposite direction (reverse bias), this is possible because of the characteristics of the silicon, or wafers inside the diode.
When a conductor / conductor positive voltage is connected to the anode and the negative voltage conductor is connected to the cathode, current flows through the diode. If the connection is reversed, the current can not flow because of the blocking characteristics of the silicon wafer, therefore the diode acts as a one-way valve (check valve) and allows current to flow in only one direction.

Figure 2. Examples of application of diode

Diode Application Examples on Motorcycles
Application / use of diodes on the electrical system of the motorcycle can be found in a series of lighting systems and charging systems that use AC generator (alternator), as shown in the figure below:

 

Figure 3. Example of Aplication Diode On Motorcycle

Based on Figure 3. above, diode (rectifier) works to change the AC current (alternating) current generated alternator into Dc (unidirectional). DC current is then passed to the battery and load (load) such as turn signal light / turn signal.
