To compensate the harmonics and fundamental reactive power, two current control methods can be considered, according to whether the regulated variables are line currents (is) or active power filter currents (if). Both methods are equivalent. In fact, the error signal at the input of the current regu ...

Introduction to Op-Amp
... A perfect op-amp would output exactly zero volts with both its inputs shorted together and grounded. However, most op-amps off the shelf will drive their outputs to a saturated level, either negative or positive even if the op-amp in question has zero common-mode gain (infinite CMRR). This deviation ...

Audio power
Audio power is the electrical power transferred from an audio amplifier to a loudspeaker, measured in watts. The electrical power delivered to the loudspeaker, together with its sensitivity, determines the sound power level generated (with the rest being converted to heat).Amplifiers are limited in the electrical energy they can amplify, while loudspeakers are limited in the electrical energy they can convert to sound energy without distorting the audio signal or being damaged. These power ratings are important to consumers finding compatible products and comparing competitors.
