Power Factor Clarified: Mathematically, the power factor involves thevoltage dropacross a component and thecurrentthat flows through it. Considering first theDC circuits, having only DCvoltage sources, theinductorsandcapacitorsbehave as short circuits and open circuits respectively in steady-state. Hence ...
The boost circuit is one of the six basic chopper circuits, a switching DC boost circuit, which can make the output voltage higher than the input voltage. It is mainly used in DC motor drives, single-phase power factor correction (PFC) circuits, and other AC/DC power supplies. Figure 6....
The main common three resonant circuits include a series-parallel resonant converter (SPRC), a series resonant converter (SRC), and parallel resonant converter (PRC) [19]. The second factor lies in a quantity of the reactive elements (amount of transfer function order). However, the third one...
In AC circuits, the power factor is the ratio of the real power that is used to do work and the apparent power that is supplied to the circuit.The power factor can get values in the range from 0 to 1.When all the power is reactive power with no real power (usually inductive load)...

Automatic Power Factor Controllers Electrical loads such as motors can cause electrical systems to be very inductive, which results in very ‘lagging power factor’ i.e. wastage of energy. The simple solution to maintain the power factor in required range is to connect or disconnect the power ...
transformer (PST), used to control energy flows on transmission lines. By adequate adjusting phase-shift of the PST, it becomes possible to increase current flow by a factor of four in the line opposite to the PST line while also maintaining voltage in the network during the de-icing period...
