Half Wave Rectifier Circuit Diagram Ncert. We ll now go through the process of how a half wave rectifier converts an ac voltage to a dc output. The main difference between half and full wave rectifier in circuit is the usage of two diodes d1 and d2.
It is a simple diode or a group of diodes which converts ac alternating current voltage into dc direct current. The output is measured across the load resistance r l. In this section let us understand how a half wave rectifier transforms ac into dc.
As you know a diode is to electric current like a one way valve is to water it allows electric current to flow in only one direction.
A high ac voltage is applied to the primary side of the step down transformer. As you know a diode is to electric current like a one way valve is to water it allows electric current to flow in only one direction. Full wave rectifier circuits are used for producing an output voltage or output current which is purely dc. During the positive half of the input cycle of ac voltage the junction diode d1 is forward biased as shown in the diagram above.
