Why Is It Common In Electrical Systems To "use Power Factor Correction Devices To Compensate For Total Reactive Power"?

When designing power distribution systems, companies first focus on the ratio of apparent power to reactive power in the system. Phase differences or waveform distortion between voltage and current generate significant reactive power. At this point, introducing capacitor bank for power factor improvement becomes a common method to compensate for the total reactive power of the circuit.

power correction device can provide or absorb reactive power to the system through external reactive components, such as capacitors or inductors, thereby compensating for the reactive power caused by inductive or capacitive loads. In this way, the voltage and current waveforms between the power supply and the load can be closer to being in phase, reducing the deviation between apparent power and active power.

In power supply design and distribution networks, the power factor correction device industrial can also reduce current distortion and improve power grid quality for systems using switching power supplies or other nonlinear loads. Whether it is passive PFC (passive correction) or active PFC (active correction), the power factor device can significantly reduce the impact of reactive power on the power grid and equipment by conditioning the current waveform to synchronize with the voltage.
