Phase Reversal in Single Stage Transistor Amplifier: In a common emitter configuration, the output voltage increases in the negative direction when the input signal increases in the positive direction and vice versa. This is called…
Phase Relation in Pure Resistor: Phase Relation in Pure Resistor - When a sinusoidal voltage of certain magnitude is applied to a resistor, a certain amount of sine wave current passes through it. We know…
Phase Relation in Pure Inductive Circuit: Phase Relation in Pure Inductive Circuit - As discussed already, the voltage current relation in the case of an inductor is given by Consider the function i(t) = Im sin…
Phase of Sine Wave: Phase of Sine Wave - A sine wave can be measured along the X-axis on a time base which is frequency-dependent. A sine wave can also be expressed in terms of…
Phase Margin Optimum: The method can be based on the phase margin in which the controller is designed to provide a minimum phase margin. The design makes use of Bode plots. The ratio of time…
Phase Locked Loop Working Principle: A Phase Locked Loop Working is basically a closed loop system designed to lock the output frequency and phase to the frequency and phase of an input signal. It is…
Phase Locked Loop Control(PLL): A PI controller ideally should provide perfect speed regulation. However, due to imperfections in sensing and control circuits, the closed-loop schemes described earlier can at best achieve a speed regulatio of…
Phase Discriminator: This Phase Discriminator is also known as the center-tuned discriminator or the Foster-Seeley discriminator, after its inventors. It is possible to obtain the same S-shaped response curve from a circuit in which the…
Phase Conversion in Transformer: Three Phase to Two Phase Conversion Transformer (Scott-T transformer or Scott Connection): Phase conversion from three to two phase is needed in special cases, such as in supplying 2-phase electric arc…
Phase Controlled Line Commutated Converters: In these Phase Controlled Line Commutated Converters, the commutation voltage, i.e. the voltage required to transfer current from one thyristor to the other, is provided by the supply lines to…
