frequency converters, which are widely used in special environments such as oil
and gas, chemical industry, and coal mines. The power frequency converter has
the characteristics of high reliability, high protection, and high efficiency,
and meets the needs of customized frequency converters.

Types of Frequency Converter
High IP Converter
Solid State Frequency Converter 50HZ to 60HZ
Because of its high cabinet protection level, the frequency converter can be
installed outdoors and is suitable for complex outdoor operations.

Power Transformation High IP Converter
High Voltage Frequency Converter 50HZ 10kV/11kV/13.8kV
Input voltage is 11kV or 13.8KV and it can output 2 or 3 curcuits which runs 2
or 3 motors at same time.

Explosion Proof VFD
Explosion Proof Variable Frequency Drives 1140V 75kW / 660V 110kW
With explosion proof certificate,this kind of VFD is allowed to run in the
undermining environment.The voltage is from 380V to 1140V.

Static Frequency Converter Applications
1. Voltage and Frequency Converter for Cooling Tower: The use of a voltage and
frequency converter on a cooling tower fan is the most useful means to control
leaving water temperature on critical process water applications. Frequency
Converter can help save energy and reduce the noise of cooling tower in non-
peak periods and benefit the life of the frequency converter components with
fewer starts, smoother starts, and built-in motor diagnostics.

2. Voltage and Frequency Converter in Mining Applications: Voltage and
frequency converter are now finding wide use in mining applications.

3. Voltage and Frequency Converter for Water Pumps: The installation of voltage
and frequency converter on water pumps can be an effective energy saving
measurement. Voltage and frequency converter can be installed on all water
pumps, including those associated with HVAC systems.

Benefits of Using Frequency Converters
1. Speed regulation and saving energy, which can save energy by lowering the
motor speed when it is not necessary to run at full speed.
2. Soft start can be used to prolong the service life of the voltage and
frequency converter.
3. The motor control system is simplified.
4. Reduce mechanical wear and loss.

How Frequency Converter Works?
Static frequency converter working principle: The electric frequency converter
mainly adopts AC-DC-AC mode, which first converts the power frequency AC power
supply into DC power supply through the rectifier, and then converts the DC
power supply into AC power supply with controllable frequency and voltage to
supply the motor. The voltage and frequency converter converts a basic fixed-
frequency, fixed voltage sine-wave power (line power) to a variable-frequency,
variable-voltage output used to control speed of induction motors.

Frequency Converter VS VFD
1.Power Supply: VFD is composed of AC-DC- AC (modulation wave) circuits.
Voltage and frequency change proportionally at the same time and can not be
adjusted separately, which does not meet the requirements of the AC power
supply. In principle, it can not be used for power supply, and VFD is generally
used for speed regulation of three phase asynchronous motor. The whole circuit
of frequency converter consists of AC-DC-AC-Filter Circuit, so the output
voltage and current waveform are pure sinusoidal, which is very close to the
ideal AC power supply. Voltage and frequency converter can output the power
grid voltage and frequency of any country in the world.

2.Load Test: VFD(variable frequency drive motor) can't use in load tests
because of high vibration and electromagnetic noise, large temperature rise,
and the instruments can't work normally. So the voltage to frequency converter
that can provide a pure sine wave output becomes indispensable power equipment
in the laboratory.

3. Converter: A VFD is not a typical converter though it has conversions inside
it. A voltage frequency converter would typically convert a DC signal to an AC
signal.

FAQs of Frequency Converter

What is a frequency converter?
The frequency converter is one of the electrical control devices that uses
frequency conversion technology and microelectronics technology to control AC
motor by changing the frequency of the motor working power supply.

The inverter is mainly composed of a rectifier (AC to DC), filter, inverter (DC
to AC), braking unit, driving unit, detection unit and micro-processing unit.
The inverter adjusts the voltage and frequency of the output power supply by
the interruption of IGBT, and provides the required power supply voltage
according to the actual needs of the motor, so as to achieve the purpose of
energy saving and speed regulation. In addition, the inverter has many
protection functions, such as overcurrent, overvoltage and overload protection,
etc.
