The main difference between a Center Tapped and Bridge Rectifier is that one uses center tapped transformer while another do not require a center tapped transformer. Both these types are full wave rectifiers but their method of converting AC input into DC is different by...

Peak Inverse Voltage or PIV is the maximum voltage appearing across the p-n junction diode when it is non-conducting. A diode do not conducts when it is reversed biased. This means peak inverse voltage is the maximum reversed biased voltage across the diode terminals when...

What is Bridge Rectifier? Bridge Rectifier is a full wave rectifier which converts sinusoidal AC input to DC. This circuit comprises of four diodes which are so connected that two diodes conducts during positive cycle of supply input whereas remaining two conducts during the negative...

A Center Tapped Full wave Rectifier is a circuit which makes unidirectional flow of current through the load during the full cycle of input voltage. Two diodes are so connected across the terminals of center tapped transformer secondary terminals that one diode conducts for positive...

The value of ripple factor of single phase half wave rectifier is equal to 1.21. Since, ripple factor is the ratio of rms value of fluctuating ac component to the average value or dc value. Its value of 1.21 means that, the ac fluctuating component...

The winding used in electrical machine can be broadly classified into two types: Concentrated Winding and Distributed Winding. Concentrated Winding In concentrated type of winding, all the winding turns are wound together in series to form one multi-turn coil. Examples of concentrated winding are field...
