Power Factor Correction: Reactive Power Compensation Methods
A power factor correction (PFC) circuit is added to a power supply circuit to bring its power factor close to 1.0 or reduce harmonics. This application note discusses the basic …
Demystifying Power Factor Compensation
Consider your power factor to be 0.85 (this is typically lagging power factor). Let us first calculate the leading KVAR (required from capacitor bank) to correct the power factor to 0.99. So the capacitor bank should switch on capacitors worth 620 KVAR to
