In half wave rectification, either the positive or negative half of the AC wave is passed, while the other half is blocked. In its simplest form this is achieved by shunting the resistor with a capacitor. However, for applications in which a constant DC voltage is not very essential, you can use power supplies with half wave rectifier. During the negative half cycle, the diode is reverse biased and it is equivalent to an open circuit, hence the current through the load resistance is zero.
