The rectifying efficiency of a half wave rectifier when the forward diode resistance is zero is approximately 40.53%. Since the half wave rectifier only rectifies half of a sin wave, the average ouput voltage is half of that of a full wave rectifier in the same conditions. It is also affected by the load resistance when the diode resistance is not zero.
This value decreases as the diode resistance increases. The average output voltage of a half wave rectifier when the diode resistance is zero is approximately 0.318*AC Input Voltage(max)) or 0.45*AC Input Voltage(RMS). This tool calculates the average output voltage and rectifying efficiency of a half wave rectifier while taking into account the forward diode resistance. Refer to Table 1-1 to see how many active elements are in each configuration.Half Wave Rectifier - Average Output Voltage and Rectifying Efficiency Calculator The number of active element legs in the Wheatstone bridge determines the kind of bridge configuration. There are three types of strain-gauge configurations: quarter-bridge, half-bridge, and full-bridge. The gauge is the collection of all of the active elements of the Wheatstone bridge. Strain-gauge configurations are arranged as Wheatstone bridges. The Wheatstone bridge configuration is used to help measure the small variations in resistance that the sensing elements produce corresponding to a physical change in the specimen. The output of a Wheatstone bridge is measured between the middle nodes of the two voltage dividers.Ī physical phenomena, such as a change in strain applied to a specimen or a temperature shift, changes the resistance of the sensing elements in the Wheatstone bridge. R1 and R2 compose one voltage divider circuit, and R4 and R3 compose the second voltage divider circuit. The Wheatstone bridge is the electrical equivalent of two parallel voltage divider circuits.
