Half Wave Voltage Doubler
A half-wave voltage doubler is a type of electronic circuit that is used to double the voltage of an alternating current or alternating signal. This half-wave voltage doubler consists of a diode and a capacitor. During the positive half cycle of the AC input, the diode allows current to charge the capacitor to a high voltage. During the negative half cycle, the diode does not allow the current while the capacitor discharges through a load doubling the voltage across the load. This circuit is simple but is not very efficient compared to other type of rectifiers.
Working of Half Wave Voltage Doubler
- During the positive half cycle the diode D1 gets forward baised and hence it conducts which charges C1 to its peak input voltage.
- During the negative half cycle the diode D1 gets reversed baised and it does not conduct and D2 gets forward baised and it conducts which transfers the charge from C1 to C2.
- The output voltage (Vout) across the C2 is approx twice of its peak input voltage.
