Full wave rectifier

This video by LearnPhysicsClasses provides a comprehensive explanation of the Full Wave Rectifier, a crucial topic in electronics. The lecture begins by contrasting the Full Wave Rectifier with the Half Wave Rectifier, highlighting how the former rectifies both positive and negative half-cycles of an input AC signal (2:35-3:02). The instructor defines the ripple factor (1:12-1:59), explaining it as the AC components present in the pulsating DC output of a rectifier. The video then delves into the two main types of Full Wave Rectifiers: Center-Tapped Rectifier (6:55-7:06): This type uses a center-tapped transformer and two diodes (7:16-7:36). The video provides a detailed explanation of its construction (9:37-10:46) and working principle during both the positive (12:26-18:08) and negative half-cycles (18:15-22:02) of the input AC signal. The concept of diode biasing (14:34-15:56) (forward and reverse bias) is clearly explained to illustrate how the diodes conduct in different cycles. Bridge Rectifier (7:08-7:13): This type uses a step-down transformer and four diodes (7:42-8:06). While briefly mentioned as part of the curriculum, the video focuses primarily on the Center-Tapped Rectifier. This video is an excellent resource for students studying semiconductor devices and rectification, especially for UP Board, CBSE, B.Tech, CUET, and BTEUP examinations, as it covers frequently asked long-answer questions. #upboard #cbse #btech #cuet #bteup #physics #electronics #rectifier #fullwaverectifier #semiconductordevices
