Active Front End (AFE), Active Infeed: energy regeneration and low harmonic
V&T EcoDriveCN® Active Front End (AFE) is a controllable rectifier with advantages such as providing bidirectional power exchange between AC and DC power and regenerating reusable power to the mains to reduce the cost of power, a fully regenerative combination of a Pulse-Width Modulated IGBT inverter with a clean power filter.
V&T EcoDriveCN® active front end AC drives are used to replace traditional brake resistors in AC variable speed drives to convert regenerative energy (excess heat) into reusable electricity.
Using V&T EcoDriveCN® AFE variable frequency drive, more than 95% of the energy is regenerated and supplied back to the mains, delivering clear energy savings.
Using V&T EcoDriveCN® Active Front End, AFE, Active Infeed, you get the following benefits:
- Simple operation, quick commission and installation
- Perfrect line disturbance/conditions
- Low harmonic, clean power
- Stable operation of motor on weak power supply systems with fluctuating voltage and frequency
- Energy saving: energy regeneration to the line supply, or to the common DC bus
- Will not interfere with sensitive equipment
- Maintains unity power factor
V&T EcoDriveCN® drives utilize the latest microprocessor and power semiconductor technology to provide the industry with economical, compact and highly flexible active front end (AFE, Active Infeed) drive packages.
V&T EcoDriveCN® Active Front End (AFE, Active Infeed) is an option for Ac frequency inverters (VSDs, VFDs) to return energy to the line supply. It provides 4-quadrant operation and reduces the total current distortion factor THD(i).
Application: crane and lift applications (hoists, long travel motion), downhill conveyors, winches, elevators, escalators, complex drive systems, test benches and high dynamic drives, pump/turbine combinations, low harmonic drives, machine tools, bag making machines, auto storage and retrieval systems, oil extraction machinery, and lathes.
