Power Factor Correction (PFC) is the process of correcting a power system’s power factor. The power factor of an AC power system should ideally be 1. When it is less than 1, the station has to pay a surcharge on its energy bill. This is because when a power factor lower than 1 is present, more power is consumed than necessary.

PFC is used to improve the power factor of a power system by reducing the amount of reactive power generated. Reactive power, also known as “wasted power,” is responsible for the decrease in power factor. Through PFC, reactive power is reduced by pre-regulating the AC voltage and current so that their phases are better aligned. This process is beneficial for both power utilities and consumers as it reduces the strain on generators and leads to cost savings from improved power efficiency.

One example of a system utilizing PFC is Robbins & Myers’ R2A20114ASP#W0. This system is designed for a wide range of applications and is particularly suitable for LED lighting and other power conversion devices with limited safety margins. Its highly efficient power factor correction topology is capable of high power density with an output of up to 500W in a single package. The system is also able to provide a wide input voltage range of only 85 – 305VAC to support both high and low power applications.

The system employs a variety of protection mechanisms to ensure safe and reliable operation. These include Over Voltage Protection (OVP), Output Short Circuit Protection (OCP), and Thermal Shutdown (TSD). Additionally, the system has an optional Under Voltage Lock Out (UVLO) function that will automatically turn off the power supply for input voltages below a certain threshold.

At the heart of the system is a high frequency, high efficiency PFC circuit that works in conjunction with a proprietary pulse width modulation (PWM) control algorithm to produce a power factor higher than 0.999. This significantly reduces the amount of current harmonics produced by the system, leading to a more efficient power conversion process. The system also includes a built-in over temperature protection circuit and active current-limiting to prevent overload and ensure maximum safety.

The R2A20114ASP#W0 also features a built-in soft start function which gradually increases the voltage output to limit inrush current at turn-on. The system also provides a wide range of dimming options including digital, analog, PWM and 1% to 100% adjustment. This makes it suitable for a broad range of applications from indoor lighting to outdoor displays.

Overall, Robbins & Myers’ R2A20114ASP#W0 is an efficient, safe and reliable power factor correction system designed for a variety of applications. Its advanced features and sophisticated algorithms provide maximum power efficiency and safety, ensuring safe operation and cost savings.
