If you any doubt about the circuit please drop it in comments we will respond you. Conventional precision rectifiers were constructed using operational amplifiers (OAs) [1]. Although this method is substantially less sensitive to stray reactances in the bridge than conventional phase-sensitive detectors, it is sensitive to gain stability and linearity of the rectifier circuits. For any input voltage the ideal Op-amp has, The phase insensitive detector is formed by averaging the magnitude of two bridge voltages. Rectifiers are essentially of two types – a half wave rectifier and a full wave rectifier. 0 Response to "Full Wave Rectifier Lab Report" Post a Comment. The process is known as rectification. Introduction. A rectifier is an electrical device that converts alternating current (AC), which periodically reverses direction, to direct current (DC), which flows in only one direction. As shown in the above figure, the full wave rectifier converts both positive and negative half cycles of the input … The purpose of this lab activity is to investigate precision rectifiers or absolute value circuits.
