Lab 5: Power Factor Correction

Prelab 5

Recall that average power absorbed by a circuit element is VrmsIrmscos(θ-φ) where θ-φ is the phase difference between the element's sinusoidal voltage v(t) and current i(t). To obtain the most efficient use of the current delivered to a load, it is desired that the load voltage and current be in phase (θ-φ = 0, PF = 1) such that average power is maximized. The purpose of this lab is to add compensation to an inductive load such that its equivalent power factor becomes close to 1.

Notes on Measurements:

Laboratory Procedure:

  1. Investigate inductive load
  2. Load power factor correction
