The Active Front End (AFE) is a controllable rectifier. Its advantages include bidirectional power exchange between AC and DC and the feed of reusable power back to the mains. The AFE uses PWM modulation to reduce current peaks and form perfect sine wave current. The power factor is corrected up to 1. The ratio between load capacity and power capacity is 1:1. In addition, the AFE eliminates high-order harmonics and provides very low harmonic current, THD<5%, while improving the power factor. Customers to not need to purchase additional electrical equipment for better power quality. The AFE also offers stable power quality, unaffected by mains power fluctuations, and supports serial connection.
Delta’s innovative AFE2000 is the product of years of experience in AC motor drive development. Designed for a wide range of application, this unit achieves outstanding energy-saving results. The AFE2000 converts excess heat (otherwise wasted) into reusable power that can be supplied back to the mains. The AFE2000 is yet another Delta product for improved efficiency and productivity. It is another step on our mission "to provide innovative, clean and efficient energy solutions for a better tomorrow".
