Power factor correction (PFC) is an important technique for energy saving, load optimization and harmonic reduction in systems based on electrical loads and power generators. It is especially important in instances where the input power distribution system lacks additional regulation, such as renewable energy systems. The FAN7930BMX is a power factor correction controller designed specifically for these types of applications. This article will explore the application fields and working principles of the FAN7930BMX.

Application Fields

The FAN7930BMX is suitable for use in a variety of industrial, commercial, and residential applications for extracting energy from power sources and driving resistive and inductive loads. This includes LED lights and electronic ballasts, appliance motors, adjustable speed drives, power distribution systems, renewable energy systems, and electric vehicle charging systems. Some of the capabilities of the FAN7930BMX include power factor correction, over-current protection, over-temperature protection, and soft start functions.

Working Principle

In order to understand the working principle of the FAN7930BMX, it is important to understand the basics of power factor correction and how it applies to power circuits. Digital power factor correction uses converter technology to improve the power factor of a system by producing an accurately controlled power waveform that improves the overall efficiency of the system. The FAN7930BMX uses an internal control algorithm that compares the output waveform of the converter to the waveform of the rectified AC input line. The controller adjusts the switching waveforms of the converter in order to maintain a good power factor. The FAN7930BMX also includes built-in over-temperature protection, over-current protection, and soft start functions.

Conclusion
