PWM Converter is synonym of Active Front-end Converter. As the PWM Converter is connected at the input side (front side) of the AC drive, it is also known as an Active Front-end Converter.
Active Front-end Converter is used to improve the power quality by improving the power factor to unity (also settable) and reduced current harmonics at input side. Also, it allows bi-directional power flow; the excess energy can be feedback to the grid (regenerative braking) rather than dissipating in resistors.
Amtech is a leading manufacturer and designer of Power Electronics products in the field of Motor Control, Automation, Power Quality & Energy Conservation and Industrial Electronics solutions. For the Power Quality segments, we have products like Active Front-end converter for the equipment level harmonic mitigation as well as grid feeding of regenerative energy. Wideband Harmonic filter, again for the equipment level harmonic mitigation. Then we have Active Harmonic filter for the plant level harmonic mitigation. The Static VAR compensator is used to compensate the reactive power at plant level. We also provide services like harmonic audit and solutions to comply with global standards IEEE–519:2014; System design, optimization and pay-back analysis; Consultancy for power quality improvement; Installation and commissioning of harmonic filters; Training in power quality and energy management and Energy audit and solutions by experienced BEE certified professionals.
