🔁 Key Relationships
PF = cos(θ) = P/S
θ = arccos(PF)
P = S × cos(θ) = S × PF
Q = S × sin(θ) = S × √(1 - PF²)
S = √(P² + Q²)

Frequently Asked Questions
What is Power Factor and why is it important?
Power Factor (PF) is the ratio of real power (P) to apparent power (S), expressed as PF = P/S = cos(θ). It measures how effectively electrical power is being used. A power factor of 1.0 (unity) indicates perfect efficiency, while lower values mean more reactive power and higher energy costs.
What's the difference between Real, Reactive, and Apparent Power?
Real Power (P) in watts does actual work, Reactive Power (Q) in VAR is stored and released by reactive components (inductors/capacitors), and Apparent Power (S) in VA is the total power supplied by the source. They're related by S² = P² + Q².
How do I improve a poor power factor?
Poor power factor (typically below 0.85) can be improved by adding power factor correction capacitors for inductive loads, or inductors for capacitive loads. This reduces reactive power demand and improves system efficiency.
What are typical power factor values for different loads?
Resistive loads (heaters): PF ≈ 1.0; Fluorescent lights: PF ≈ 0.5-0.95; Induction motors (full load): PF ≈ 0.85-0.95; Induction motors (light load): PF ≈ 0.2-0.6; Power supplies: PF ≈ 0.6-0.99.
Can I use this converter for three-phase systems?
Yes, the power factor relationships remain the same for three-phase systems. Just ensure you're using total three-phase power values (P, Q, S) rather than per-phase values for accurate calculations.
Why can't the power factor exceed 1.0?
Power factor is defined as cos(θ), and since cosine values range from -1 to +1, power factor cannot exceed 1.0. A power factor of 1.0 represents perfect efficiency where all apparent power becomes real power.
