Harmonic, displacement and input power factor

Click For Summary
The discussion focuses on calculating the harmonic factor, displacement factor, and input power factor for a single-phase half-controlled bridge rectifier connected to a 120V 60Hz AC supply with a thyristor delay angle of 60 degrees. The input power factor is derived using the formula PF = Is1/Is2*cosψ, where ψ is related to the circuit's inductance (L) and resistance (R). Participants seek clarification on the values of L and R to accurately compute ψ. The urgency of the request indicates a need for quick solutions to these electrical parameters. Understanding these factors is crucial for optimizing the performance of the rectifier circuit.

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?
