When a sinusoidal voltage is applied to an inductor, the voltage leads the current by one-fourth of a cycle, or by a 90º phase angle. Current lags behind voltage, since inductors oppose change in current. Changing current induces a back emfV= −L(ΔI/Δt). This is considered to ...
As the circuit shown in the figure, the line voltage of balanced three phase source is U˙AB=380∠30oV, the frequency of the source is f=50Hz. The total power of motor is PD=1.7kW, cosφD=0.8(inductive). The impedance of balanced three phase load is Z=50+j80Ω(delta connection)....
A push-pull end stage (16) controls the flow of current through the load (12). Connected in series with the load (12) is a measuring resistor (11), the voltage drop of which, as an actual current value, is applied along with a command current value to a comparison stage (23, 34)...
A low power, fast rise time current driver for an inductive load such as a sense-inhibit line of a magnetic core memory includes a transformer having a secondary thereof coupled to drive a load and the primary coupled to be driven by a constant voltage during steady state conditions. A char...
