A rectifier is a device that converts alternating current into direct current.
Half wave rectifier:
In this rectifier, the PN junction diode is connected to an input AC supply with the help of a primary coil, which will induce an emf in the secondary coil and ultimately the output is taken across the load resistance (RL).
Let at any instant S1 is positive and S2 is negative. Due to this polarity the junction diode is forward biased so it will start conducting and output is obtained. Continue reading “Half wave rectifier operation”
