Diodes – Rectifiers – Single: CES388,L3F Application Field and Working PrinciplesA commonly used single rectifier, CES388,L3F, falls under the category of diode rectifier which consists of a single diode. It is used in various application fields due to its capability of rectifying highly alternating current signals. This article discusses the application field and working principle of CES388,L3F in detail. The CES388,L3F rectifier is mainly employed in power electronics engineering, audio and signal processing as well as telecommunication. In power electronics engineering, it is mainly used for controlling and protection of circuits, mainly in the applications falling under the range of 50-60Hz, such as motors and professional drills. Although the rectifier can rectify alternating currents, it is not suitable for supplying power to circuits operating at higher frequencies because of its poor regulation capacity. In audio and signal processes, it is mainly used for producing voltage that are with near-zero distortion and without dropouts. Rectification of voltage is important in audio systems to obtain the desired signal-to-noise ratio. This rectifier is also used in telecommunications and electronic instruments, carrying out switching operations with considerably low losses of power.The working principle behind the functioning of this rectifier is based on the behaviour of the diode in a conducting and non-conducting state. When the alternating signal is switched to the rectifier, the diode contains two statuses, conducting or non-conducting. In conducting state, the electrons move from the cathode towards the anode and the rectified current flows from anode to cathode. When the diode faces non-conducting state, the current flow is reversed, causing positive voltage at anode and negative voltage at cathode. The target of rectification lies in separating the peaks of the AC current waveforms that create the majority of the distortion in amplitude-modulated signals. The CES388,L3F rectifier consists of a single diode, hence it can only rectify half of the waveform. Therefore, two or three diodes are usually employed for rectifying both the positive and negative half waveforms. Generally, there are various types of rectifiers used in different application fields. CES388,L3F, being a single rectifier, provides efficient rectification of alternating signals, due to its fast switching speed, low forward voltage Drop optimization and low current leakage capabilities. Moreover, it is also capable of producing low-distortion and free-dropout voltage for audio and signal processing. It is a suitable component for power electronics engineering, audio and signal processing and telecommunication.
