Measure the input voltage V 1 and the output voltage V 2 using both the voltmeter and the oscilloscope. Theoretical Background: Rectifiers are diodes used to change ac into dc. Do the exercise in the analysis section. Wire up the half wave rectifier circuit without capacitor after testing all the components. You will mostly use electrolytic and ceramic capacitors for your experiments. it can be measured by RF = v rms / v dc. Because only one half of the input waveform reaches the output, mean voltage is lower. <>>> And, a diode works and allows current in only one direction and blocks it in another one. Observe the transformer secondary voltage waveform and output voltage waveform across the load resistor, simultaneously on the CRO screen. �f^ ���v`�ę1��� 3-s�����zPߺT����o�WV��ΔR����Z��s��>�"��G�.��j�R�ֵ����=��'����汨�w7���-�s�~v��j�k���bB� �e�l�o�V���*D�����y�� ." 3.

The question logically arises as to which configuration is the best choice for a given application. 1. There are two types of rectifiers, half wave, and the full wave. The half-wave rectifier has both positive and negative cycles. 1.4.PROCEDURE: 1. Additionally they have high contents of harmonics, which are difficult to filter out and to smooth out the ripple in the rectified AC power. This value represents one half of the non-tapped secondary, as one half of the secondary winding was devoted to the top half of the wave while the other half was for the lower half of the function. Converting I dc into its corresponding I m value and substituting in the percentage of regulation formula we get. ���y�|�_:�ɟE*�i ��w��w�J�X��u�r@Ω/�e|I�4r@�6�tF�cj���b�=cƞEr�$Ϩ #�-�Fdl�"�/�L��4��i��$/|�%��6UI��]���TR��ăO����ǧ*��ۿ�%d�M}�JMrW/�!C>���" �β��}7�"�e����{�|��` While half-wave and full-wave rectifiers deliver a form of DC output.
