In ac circuit power factor is
WebApr 18, 2024 · Power factor correction (also known as PFC or Power Factor Improvement) is defined as a technique used to improve the power factor of AC circuits by reducing the reactive power present in the circuit. Power factor correction techniques aim to increase the efficiency of the circuit and reduce the current drawn by the load. WebThe power factor of ac circuits with linear loads lies between -1 to 1. Generally, it is considered that if a system exhibits a power factor closer to 1, then such systems are said to be stable. We will discuss the various …
