Power of an alternating current circuit is the ratio of true power dissipation to the apparent power dissipation in the circuit. Learn more about Power Factor visit BYJU'S
entitled SEMICONDUCTOR CIRCUIT DEVICE HAVING AN INSULATED-GATE TYPE TRANSISTOR, instruct the use of resistive, capacitive and reactive (transistor/diode) elements to reduce the parasitic capacitance within a control circuit that modulates a power FET when the two systems are embedded in the same semico...
k is a geometrical factor related to the source electrode geometry, and, ρDrain is resistivity of the semiconductor drain comprising layers 304 and 306. The gate length Lgate, when viewed in cross-section, is the width of the gate electrode 112 as depicted in FIG. 5A. Similarly, the gate...
FIGURE 7 Open in figure viewerPowerPoint Equivalent magnetic circuit of Figure 6 To derive magnetizing inductance, which determines the core loss of the transformer, a following formula is used under I2 = 0: (10a) (10b) From (10b), it is noted that coupling factor between primary and se...
8. Amplitude on the EXTAL pin after startup is determined by the ALC block, that is the Automatic Level Control Circuit. The function of the ALC is to provide high drive current during oscillator startup, but reduce current after oscillation in order to reduce power, distortion, and RFI, ...

Power Factor - Basic Introduction - Reactive and Apparent Power. What is difference between real power and apparent power? The power dissipated by a loadis referred to as true power. ... Total power in an AC circuit, both dissipated and absorbed/returned is referred to as apparent power. Ap...
For example, such a device displaying a 10 dB return loss may show more than the calculated 0.7 dB increase in gain when finally matched to −20 dB return loss. 2. Circuit losses can play havoc with the k-factor, and especially the frequency where it crosses unity. In practice, ...
When we calculate lower and higher frequency such that power becomes half in LCR circuit we end up with two value. For a complete derievation please see here. I have copied relevant information below: Resonant frequency: XLωrL−1ωrCωr=XC=0=1LC−−−√XL=XCωrL...
An important parameter of resonators used in wireless power transmission systems is the Quality Factor, or Q-factor, or Q, of the resonator, which characterizes the energy decay and is inversely proportional to energy losses of the resonator. It may be defined as Q=ω*W/P, where P is the...
