The supplier of frequency converter braking unit reminds you that frequency converter speed regulation technology has been widely used in the industrial field. In many applications of variable frequency speed regulation, regenerative energy is often generated. Currently, most of the ways to handle the regenerative energy generated during the variable frequency speed regulation process are through energy consuming braking units - that is, by installing high-power braking resistors and consuming this energy through the heating of the braking resistors. The use of energy consuming braking units to process regenerative energy will consume a large amount of electrical energy in vain, and even emit a large amount of heat, polluting the operating environment of electromechanical equipment and significantly reducing its service life.
The PSG energy feedback system replaces the resistance braking method with energy feedback technology, which converts the regenerated energy generated during the variable frequency speed regulation process into clean electrical energy through inversion and harmonic processing, and feeds it back to the power grid for use by surrounding electrical equipment. Replacing resistance braking with PSG energy feedback can bring many benefits:
1. Adding PSG energy feedback can quickly eliminate the pumping voltage of the frequency converter, greatly improving braking efficiency;
2. The energy-saving effect of PSG energy feedback is very significant, with a comprehensive energy-saving rate between 20% and 60%;
3. Without high-power heating elements, the temperature in the computer room drops, saving electricity for cooling equipment such as air conditioning, achieving better energy-saving effects;
Without high-power heating elements, it is equivalent to eliminating a safety hazard in the vicinity of a computer room or equipment;
