Digital Active Power Conditioner

The industrial and commercial applications use of devices like computers, UPS systems, AC/DC drives, energy saving lamps, rectifiers, high density DC power supplies, solid state lighting ballasts, SMPS, etc., is on rise. These devices draw non-linear type of current from the electrical supply. This leads to what is called as harmonic pollution, which has bed effects on the quality of power and it creates problems for user as well as the supply authority. DB Power Electronics (P) Ltd, a three-decade-old premier power electronics company in India, has come to the rescue of all the harmonics affected users. Their state-of-art designed digital active power conditioner, named as Swan, is a unique answer to all the harmonic problems. Swan dynamically eliminates the harmonics from the utility power source and improves on the power factor nearer to unity. This active filter is based on synchronous rotating reference frame principle and uses 32-bit DSP controller, giving stable, easy to upgrade, flexible performance over longer period of operational life. It has wide applications areas and can be installed along with UPS, AC drives, at the source, at the large computer facilities, and the near main input. Excellent applications could be found with the complex mix of load as seen in datacenters, hospitals and process automation. Working principle: Swan uses latest technology to eliminate harmonics injected into the mains supply by non-linear loads, as well supplies inductive power demanded by the load so as to correct input power factor to near unity.
