The supply circuit supplies A.C. current whose magnitude is independent of the load and allows the stabilised load current to be varied smoothly from zero to a maximum value, without requiring that the reactive elements in the circuit be synchronously regulated. Each phase has a capacitor and ...

Is this circuit’s overall behavior capacitive or inductive? In other words, from the perspective of the AC voltage source, does it “appear” as though a capacitor is being powered, or an inductor? Now, suppose we take these same components and re-connect them in parallel rather than serie...
AC - Active, Reactive and Apparent Power Real, imaginary and apparent power in AC circuits. The required power supply to an electric circuit depends on the active power - real electrical resistance power consumption in circuit reactive power - imaginary inductive and capacitive power consumption in ...
components in the load that is powered by the AC circuit. In a purely resistive load (incandescent lights for example), the apparent power is equal to the true power and the amount of VAs and watts used would be equivalent. However, in more complex loads, such as computers (which UPSs ...
Higher harmonic power components and fundamental wave reactive power components are derived from a load voltage and current, using theory (instantaneous p-q theory) regarding instantaneous real power and instantaneous imaginary power. Ga... Y Tanoue,A Kawaguchi - US 被引量: 31发表: 1992年 An Alt...
In a purely reactive circuit, the current leads the voltage or lags it depending on the type of reactance (inductive or capacitive). In an AC circuit having both resistive and reactive components, the power consumed can be calculated using the following formula: ...

摘要: In a dual active bridge (DAB) dc–dc converter, modulating the phase-shift ratios can suppress reactive power and increase the efficiency under non-unity voltage gain conditions. Derivation of the optimal phase-shift ratios to achieve the minimum reactive...
