Differences Between APFC and MPFC: A Comprehensive Guide

Power factor correction is essential for enhancing energy efficiency, minimizing power losses, and extending the life of electrical devices in today's electricity grid. APFC (Automatic Power Factor Controller) and MPFC (Microprocessor-based Power Factor Controller) are two widely used systems for power factor correction. They perform similar functions but differ in working principles, features, and applications.

This blog will discuss what the APFC is, what the MPFC is, how they work, benefits, and comparisons. We will also cover APFC and MPFC by Lauritz Knudsen Electrical & Automation, which are commonly used in industrial and commercial power management systems.

What is APFC?

APFC stands for Automatic Power Factor Controller. This can be achieved by monitoring the reactive power in the network and switching on/off capacitor banks as needed. APFC is utilized in electrical applications such as industries, commercial buildings, and power stations to increase power efficiency and minimize energy losses.

APFC Working Principle

The APFC operating principle is based on the real-time monitoring of the power factor using current and voltage sensors. The capacitor banks are switched on and off by the controller when the power factor is less than a preset value, indicating that reactive power must be compensated. When the desired power factor is reached, the system switches off unneeded capacitors to prevent overcorrection.

What is MPFC?

MPFC (Microprocessor-based Power Factor Controller) MPFCs offer a more intelligent, efficient, and functionality-rich solution compared to traditional APFC systems.

MPFC Working Principle

The MPFC working process relies on a digital processor module that constantly and instantaneously examines power quality, load fluctuations, and occurrence of harmonic distortions. In contrast to APFC, which simply switches capacitors as a function of an algorithm, MPFC works in a dynamic manner in response to changing load conditions and encourages a smart power factor correction. This type of system usually combines advanced algorithms and real-time data logging with remote monitoring capabilities, making them suitable for more dynamic and high-precision power management solutions.

Key Differences Between APFC and MPFC

Benefits of APFC

- Gets Vibration and Harmonics Sorted: Frequency variation leads to an optimal role of power factor maintaining the use of electricity closer to a value of 1.

- Reduces bills when electricity is Charged: Avoids penalties charged by the utility company for low power factor.

- Improves Equipment Durability: Less voltage sag does good for the life of electrical equipment.

- Reduces Reactive Power Losses: Preserves a synchronized consumption of electrical energy.

- Effective Operation: Needs low human mediation for power factor correction.
