The use of positive feedback results in a feedback amplifier having closed-loop gain greater than the open-loop gain. It results ininstabilityand operates as an oscillatory circuit. An oscillatory circuit provides a constantly varying amplified output signal of any desired frequency. The Oscillatory ...
Let the motion of a given point be described by the equation: (1.1)x=X sin ωt where x is the displacement from the equilibrium position, X the displacement magnitude of the oscillation, ω the frequency in rad/s and t the time. The quantity X is the single-peak amplitude, and ...

A signal consisting of two sinusoidal signals is considered to be periodic, if the ratio of their periods is a rational number. (a) The period of 2 cos(6t) (i.e.,T1) can be obtained by solving the equation 6t=2πt/T1. We then have T1=π/3. The period of 3 sin(4t) (i.e...
The basic idea is to generate a specific order of sinusoidal harmonic signal and inject it into the PFC current control loop. The magnitude of the sinusoidal harmonic signal can be dynamically adjusted based on operating conditions, such as load and input voltage, to maximize the harmonic ...
