Abstract/Summary

The power factor controller (PFC) prototype will incorporate the following features:

a. Switching capacitors sized in binary ratio to compensate power of varying loads.

b. Zero crossing detection circuit to prevent transient circuit effects.

c. A circuit that quickly measures the load current and load voltage to be able to determine the power factor of the load.

d. A display of switch and capacitor failure and provision of best compensation at these conditions.

e. Capacitors sized in binary ratio to compensate power of varying loads.

We also include a comparative assessment of the four methods of compensation used.

This project is a model of a microcontroller based power factor correction device that allows reduction of electric current required by the load. The design primarily consists of the following: microcontroller used for implementation of all control strategy, capacitors sized in binary ratio to provide capacitive current, solid-state relays as switch for each individual capacitor and opto-isolators as current sensing element to determine the capacitor and/or Solid-State Relay SSR failure.
