What Is The Meaning of Power Factor in Battery Chargers?
Power factor is the ratio between the kW and the kVA drawn by an electrical load where the kW is the actual load power and the kVA is the apparent load power. it is a measure of how efficiently the load current is being converted into useful work output.
What Is Active Factor Correction of battery chargers
The power factor correction (PFC) circuit is designed to draw a sinusoidal current from the AC input line that is exactly in phase with the input voltage. As a result, the converter exhibits a power factor that is very close to unity or one, which is ideal.
