In a three-phase halfwave rectifier, the ratio of average output voltage to per phase maximum AC voltage is
A single-phase half-wave rectifier is a type of circuit that converts AC voltage into DC voltage.
During the positive half-cycle of the AC voltage, the diode in the circuit conducts and allows current to flow through the load.
During the negative half-cycle of the AC voltage, the diode blocks current flow and the load is effectively disconnected from the AC source.
The output voltage of the half-wave rectifier is the voltage across the load resistor, which is equal to the voltage across the diode during the conducting half-cycle.
The peak voltage of the AC source is the maximum voltage that occurs during the positive half-cycle of the AC voltage.
The average DC output voltage of the half-wave rectifier can be calculated by multiplying the peak voltage by a factor of 0.827.
DCavg = 0.827 × Vpeak
Ratio of average DC output voltage to per phase maximum AC voltage
= DCavg ⁄ Vpeak = 0.827 V
