Reactance bridge
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 … WebThe common methods or techniques used for impedance measurements are bridge method, resonant method, I-V method, RF I-V method, network analysis method and auto balancing bridge method. As we know impedance is very important parameter. It is used to characterize electronic components and circuits.
