What is Peak Inverse Voltage?
- Peak inverse voltage in the diode is the peak value of the inverse voltage across the diode in reverse bias condition. Consider the circuit shown below to calculate the PIV of the silicon diode or peak inverse voltage of the diode.
- PIV of Diode = Esm.
- PIV = 2Esm – 0.7.
What is being filtered by the capacitor in a full wave rectifier?
Full Wave Rectifier with Capacitor Filter. The main function of full wave rectifier is to convert an AC into DC. As the name implies, this rectifier rectifies both the half cycles of the i/p AC signal, but the DC signal acquired at the o/p still have some waves. To decrease these waves at the o/p this filter is used.
What is the value of PIV for half wave and full wave rectifier?
Comparison Chart
| Parameters | Half Wave Rectifier | Full Wave Rectifier |
|---|---|---|
| Peak inverse voltage (PIV) | Maximum value of supplied input | Twice the maximum value of supplied input |
| Peak factor | 2 | 1.414 |
| Form factor | 1.57 | 1.11 |
| Average current value | Imav/π | 2Imav/π |
What is filter circuit in rectifier?
The filter is a device that allows passing the dc component of the load and blocks the ac component of the rectifier output. Thus the output of the filter circuit will be a steady dc voltage. The filter circuit can be constructed by the combination of components like capacitors, resistors, and inductors.
What is filtering circuit?
A filter circuit is one which removes the ac component present in the rectified output and allows the dc component to reach the load. The following figure shows the functionality of a filter circuit. A filter circuit is constructed using two main components, inductor and capacitor.
