The medium voltage Fuji Ac drives is the best option for cutting emissions and energy use. This equipment is frequently used to guarantee the smooth running of nearly all standard motors for pumps, compressors, and fans.
At very high power ratings, medium voltage motors function exceedingly well. In this instance, controlling the pace and ensuring the installation starts gently are of utmost significance. Many individuals believe that purchasing soft starters and certain frequency converters are the first step in finding a solution to this issue.
The product regarded as being the most energy-efficient is medium voltage AC drives. This fixture’s existence of a voltage/frequency control method and a variety of warning and protection capabilities makes it stand out from the crowd.
A VFD is a medium voltage drive since it depends on the working voltage, although some VFDs use power cell parallel connections with dry-type transformers as their internal working principle. Input: 6.6KV, output: 6.6KV, converter within 3 phases, each 690V, to each power cell. FRENIC4000 Series Small-to-medium capacity DC link inverters, FRENIC4600FM5e Fuji Electric, etc are types of MV Drives Series.
What is the difference between LV, HV, Fuji Ac Drives and MV Drives?
Medium supply voltages are frequently used in sizable industrial complexes and companies that demand a lot of power. Voltage and current are inversely related, according to electrical variation analysis. As the voltage rises, a reduction in current signals the end of the process.
Higher voltage-capable motors and electrical machinery use less power and are more cost-effective to run.
Low voltage is a term with several connotations in the electronic and electrical fields. Anything that is less than 600 volts is often regarded as low voltage. Due to their unique characteristics, they are also instrumental in industries.
Utilisation of MV Drives?
The power output of medium-voltage (MV) AC drives is hundreds of times greater than that of their smaller, more prevalent low-voltage (LV) cousins, enabling control of enormous, multi-megawatt electric motors that power the largest industrial loads found in mines, power plants, or metal processing plants.
MV drives work at higher supply voltages to achieve reduced losses and employ smaller cables, which add up to superior overall drive efficiency and lower system cost.
Although not all versions are enormous, MV drives provide more than simply size. Their selection for certain applications and consumers is also influenced by other considerations, such as control designs that contain harmonics mitigation.
Depending on the industry, “medium voltage” might mean several different things. For motor drives, there is considerable agreement on the range from 600 V to 15 kV; in Europe, the MV threshold is 1 kV. However, below 2.3 kV, there aren’t many genuine drive items.
While Europe and the rest of the world favor 3.3 and 6.6 kV, MV drive inputs in the Americas generally vary from 2.3 to 4.16 k

Frenic 4600 Series
A set of medium voltage IGBT inverters called Frenic 4600 are environmentally beneficial.
Through energy conservation and motor operation stabilization, it improves the efficiency and power factor of medium voltage motors. The multi-phase diode rectifier technology reduces harmonics on the side of the power source. The unique multi-level PWM control technology from Fuji Electric makes it possible to regulate even simple motors.
It offers a high power factor on the power supply (95 percent or greater). It is possible to do away with output transformers, which increases overall efficiency. Using a single-phase, 3-level inverter with fewer inverter cells results in high dependability. Functions for sensorless vector control guarantee steady operations despite variations in load. For rapid reaction and great precision, the control device incorporates a 32-bit MPU.
