Micctech Frequency converter

Frequency converter is a power control device that uses frequency conversion
technology and microelectronics technology to control AC motors by changing
the frequency of the motor's working power supply.
The Micctech frequency converter is mainly composed of rectifier (AC to DC),
filtering, inverter (DC to AC), braking unit, drive unit, detection unit and
micro-processing unit. The inverter adjusts the voltage and frequency of the
output power supply by the opening and closing of the internal IGBT, and
provides the required power supply voltage according to the actual needs of
the motor, thereby achieving the purpose of energy saving and speed
regulation. In addition, the inverter has many protection functions. , Such
as overcurrent, overvoltage, overload protection and so on. With the
continuous improvement of industrial automation, frequency converters have
also been widely used.
The energy saving of the frequency converter is mainly manifested in the
application of fans and water pumps. After the fan and pump load adopts
frequency conversion speed regulation, the power saving rate is 20% to 60%.
This is because the actual power consumption of the fan and pump load is
basically proportional to the third power of the speed. When the average
flow rate required by the user is small, the fan and pump adopt frequency
conversion speed regulation to reduce the speed, and the energy-saving
effect is very obvious. However, traditional fans and pumps use baffles and
valves for flow adjustment, the motor speed is basically the same, and the
power consumption does not change much. According to statistics, the
electricity consumption of fans and pump motors accounted for 31% of the
national electricity consumption and 50% of the industrial electricity
consumption. It is very important to use variable frequency speed regulation
device on this kind of load. At present, the more successful applications
include constant pressure water supply, various types of fans, central air
conditioners and frequency conversion speed regulation of hydraulic pumps.
