Aim:
To construct half wave rectifier, full wave rectifier with center-tapped transformer, full wave bridge rectifier circuits and calculate the ripple factor of the rectified outputs.
Selection of components and equipment ranges: -
• Check the rating of the transformer available in the laboratory. And measure the voltage at secondary winding of the transformer.
• Peak Inverse Voltage of the diode should be greater than or equal to Vm, where Vm is the max voltage at secondary winding of the transformer.
• Criteria to select RL is, current in the circuit I is limited to be less than IFmax of the diode, voltage across RL is (Vm-VD)/I. Calculate RL value and wattage. Usually RL is taken in K
