The FGI-Tech's 3kV medium voltage AC drives, feature a unique technology that allows FGI to offer a simple, flexible and reliable drive solution. Building on many years of experience, FGI has demonstrated capability as innovator with an imaginative approach to the design and development of high performance electric power systems, enabling greater affordability, efficiency and reliability. The MV VFD drives are widely used in fans, compressors, pumps and so on. FGI develops the high quality medium voltage drives.  


Structure





HMI: Provide users with friendly all-round document operation interface, responsible for dealing with information.


Power cabinet


Each phase is connected in series by a multi-level unit;
Unit standardized structure, 3kV/6kV/10kV unit junction is the same;
The unit communicates with the control cabinet through the optical fiber to control good performance.


Control cabinet


The control core is based on DSP+FPGA, the system is powerful and can meet the customer's needs to the greatest extent;
Independent main control box, plug-in control board, easy to install and maintain;
Rich interface with multiple choices.


Operating Principle


     


The medium voltage drive is composed of switch cabinet, phase shift transformer cabinet, power unit cabinet control cabinet. Among them, the switch cabinet is different according to different sites.The equipment adopts the high-high voltage source type inverter circuit structure, the power units are connected in series, the output is superimposed into high voltage, and directly output to the high voltage motor.
