Digital Tv Frequency Converter

digital tv frequency converter (also known as adjustable-frequency drives (AFD), variable speed drives (VSD), variable-voltage/variable-frequency (VVVF) drives, AC drives, micro drives or inverter drives) are devices used in electro-mechanical drive systems that consist of an AC motor, a main drive controller assembly, as well as a drive or operator interface. The type of drive controls AC motor speed and the torque of the drive system by varying the motor input frequency and the voltage.

digital tv frequency converter can be used in various kinds of applications that range from small appliances to large compressors. Drive systems that use VFDs can have a higher level of efficiency compared to systems that use throttling control of fluid flow.

The wide selection of digital tv frequency converter from Alibaba.com include various low- and medium-voltage DC-AC and AC-AC topologies, including voltage-source inverter (VSI) drive topologies, Current-source inverter (CSI) drive topologies, six-step inverter drive topologies, cycloconverter or matrix converter (MC) topologies, load commutated inverter (LCI) drive topologies, and Doubly fed slip recovery system topologies.

VFDs can be used across a number of fields, and are most commonly used to control the speed in conveyors systems, pump speeds, blower speeds, machine tool speeds, and a number of other applications that require speed that is variable and variable torque.
