What is the importance of ripple factor?

Ripple factor ripple factor is very important in deciding the efficiency of the rectifier .ripple factor give the total power converted AC input to the DC output. Ideal ripple factor should be zero and power factor 1. Ripple factor of half wave rectifier 1.21 and full wave rectifier is 0.48.

Define the efficiency of a rectifier?

The conversion efficiency n of a rectifier ckt is generally defined as Na= dc power delivered to the load/ ac power input to the rectifier ckt. Or n = Pdc/Pac


What is the use of transformer utilisation factor?

It tells us how much is the transformer utilised in a given process. For a rectifier,TUF =(D.c.power delivered to the load)/(power rating of transformer secondary)

Rectifier


4 What is the difference between a transformer and a rectifier Which are found in a PC power supply?

A rectifier is a device that converts alternating current to direct current. A transformer is a device that changes the ratio fo current to voltage. A rectifier is found in a PC power supply.

Where you can use full wave rectifier?

Basically , rectifier is used to convert a.c into d.c . The bridge rectifier is used in all power supply section of all device which are operated on D.C supplly. For example in TV the circuit board is operated at 12 V D.C. so we need dc supply which is provided by rectifier. All SMPS ( Switched Mode Power Supplies) uses Bridge rectifier.


Which provide more power and why full wave or half wave rectification?

full wave rectifier, because in half wave rectifier only one p-n junction diode Ans 2. In full wave rectifier both negative & positive cycles are rectified , but , in half wave rectifier only the positive or the negative cycle is rectified . That's why full wave rectifier provides more power .


How a rectifier transformer deffer from a power transformer?

rectifier transformer converts acinto dc.but,power transformer convert step up or step down ac energy without changing frequency
