Connecting Wires

Half Wave Rectifier

Circuit Diagram:

Output:

Page 6: BPE (Lab Manual)

Observations & Calculations:Vmax = 4.35125 V

Vmin = -6.75997 V

VDC = 0.318 * Vmax = 0.318 * 4.35125

= 1.3837 V

Vrms = 0.707 * Vmax = 0.707 * 4.35125

= 3.076

Vac = [Vrms2 – Vac

2]1/2 = 2.747 V

Ripple Factor = R.F. = Vac / VDC = 2.747 / 1.3837

R.F. = 1.98

Full Wave Bridge Rectifier

Circuit Diagram:

Page 7: BPE (Lab Manual)

Output:

Observations & Calculations:Vmax = 3.7182 V

VDC = 2 * 0.318 * Vmax = 0.318 * 3.7182

= 2.3618 V

Page 8: BPE (Lab Manual)

Vrms = 0.707 * Vmax = 0.707 * 3.7182

= 2.62906 V

Vac = [Vrms2 – Vac

2]1/2 = 1.1549 V

Ripple Factor = R.F. = Vac / VDC = 1.1549 / 2.3618

R.F. = 0.498

Comments:From the above experiment, it is clear that the ripples and hence the ripple factor

decrease, as the value of capacitance is increased.
