A Maxwell bridge is a modification to a Wheatstone bridge used to measure an unknown inductance (usually of low Q value) in terms of calibrated resistance and inductance or resistance and capacitance. When the calibrated components are a parallel resistor and capacitor, the bridge is known as a Maxwell bridge. It is named for James C. Maxwell, who first described it in 1873. Web12-2 where V MAX is the secondary phase-to-neutral peak voltage, V f-N rms its rms value, and ω is the angular frequency of the mains power supply. It can be seen from equation (12.1) that changing the firing angle α, the load average voltage V D is modified. When α is smaller than 90°, V D is positive, and when α becomes larger than 90°, the average dc …
