Half-wave rectification

Half-wave rectification

If a source of alternating current is connected in series with a semiconductor diode the output from the circuit will flow in one direction only in a series of pulses (Fig. 45.9).

This is called half-wave rectification. The variation in the input and output voltages with time may be seen by connecting the input and output terminals, in turn, to a cathode ray oscilloscope (eRO). If a double-beam oscilloscope is available, the two voltage traces may be viewed and compared simultaneously. The load, shown as R in these diagrams, represents any circuit which is being supplied from the output.
