Harmonic, displacement and input power factor

Click For Summary
SUMMARY

The discussion focuses on calculating the harmonic factor, displacement factor, and input power factor for a single-phase half-controlled bridge rectifier operating on a 120V, 60Hz AC supply with a thyristor delay angle of 60°. The input power factor (PF) is derived from the formula PF = Is1/Is2*cosψ, where ψ is defined as ψ=arctan(wL/R). The values of inductance (L) and resistance (R) are critical for determining ψ and subsequently the input power factor.

1. A single phase half controlled bridge rectifier operated from a120V 60Hz ac supply. The load
current with an average value of I is continuous and negligible ripple content. If the delay angle
of thyristors is 60, calculate,
i) The harmonic factor of the input current
ii) The displacement factor
iii) The input power factor



PF = Is1/Is2*cosψ



What is ψ? i think that ψ=arctan(wL/R), if so what are L and R?
