Half-wave rectification can be achieved with a single diode in a one-phase supply, or with three diodes in a three-phase supply. As can be seen, as a result of the capacitor (filter), the output voltage is not as before, meaning that the voltage does not vary between zero and the peak value of the alternating current. The average output voltage is higher than for half wave, the output of the full wave rectifier has lesser ripple than that of the half wave rectifier producing a relatively smoother output waveform. In half wave rectification, either the positive or negative half of the AC wave is passed, while the other half is blocked. Half-wave Rectifier with Capacitor Filter – Waveform The value of the discharge time constant (C*RLoad) being very large, the capacitor ‘C’ will not have enough time to discharge properly.
