With the help of a circuit diagram, explain how a full wave rectifier gives output rectified voltage corresponding to both halves of the input ac voltage.
Marking-scheme solution
Explanation
Suppose the input voltage to A with respect to the centre tap at any instant is positive and B being out of phase will be negative so , diode \(\displaystyle \mathrm{D}_{1}\), gets forward biased and conducts while \(\displaystyle \mathrm{D}_{2}\) being reverse biased is not conducting. For the next half cycle of input voltage, the polarities are reversed and the diode \(\displaystyle \mathrm{D}_{2}\) conducts being forward biased.All Semiconductor Electronics: Materials, Devices and Simple Circuits questions2023 question paperNCERT solutions: Semiconductor Electronics: Materials, Devices and Simple CircuitsPractice Semiconductor Electronics: Materials, Devices and Simple Circuits →
