The demonstration is aimed to understand and analyze silicon diode rectification. The apparatus contains full wave and half wave rectification circuitries. A selection switch is also provided to select between the two circuitries.
An alternating voltage is supplied on the input terminals and the rectified output is observed on the output terminals. The LabView VI provided with the demonstration requires a DAQ card with one analog voltage output, one differential voltage input and one absolute voltage input channels. A sinusoid of amplitude up to 10V and frequency up to 400Hz is supplied through the analog output channel Ao0. The output of the rectifier circuit is received through differential channels Ai0 and Ai4. The output signal is also read back as a reference through the Ai1 input channel. The wiring has to be made according to these requirements for the VI to work.
