Rectifier diodes play a crucial role in power supplies by converting alternating current (AC) to direct current (DC), which is essential for the operation of most electronic devices. In an AC power supply, the voltage alternates between positive and negative cycles. Rectifier diodes, with their unidirectional current flow property, allow current to pass only during the positive half-cycles, effectively blocking the negative half-cycles. This process is known as rectification.

The automotive engine cam phaser is a sensor device whose main function is to collect the position signals of the air distribution camshaft and input these signals into the electronic control unit (ECU). By means of these signals, the ECU is able to identify the position of the upper compression stop of cylinder 1, thereby enabling sequential injection control, ignition timing control, and deflagration control of the engine. In addition, the signals from the camshaft phaser are used to recognise the first ignition moment at engine start to ensure that the engine can be started smoothly. The operating state of the phaser camshaft directly affects the performance and operating efficiency of the engine, so their proper functioning is essential to ensure stable engine operation.
