What is the difference between transformer and inverter?
What is a transformer? A transformer is a device that uses electromagnetic induction principle to change AC voltage.
The main components are primary coil, secondary coil and iron core (Core).
The main functions are: voltage conversion, current conversion, impedance conversion, isolation, voltage stability (Magnetic saturation transformer)Wait.
According to the purpose can be divided into: power transformer and special transformer (
Electric Furnace transformation, rectifier transformation, power frequency test transformer, regulator, mine transformation, audio transformer, medium frequency transformer, high frequency transformer, impact transformer, instrument transformer, electronic transformer, reactor, transformer, etc).
What is the inverter, inverter (Frequency conversion driver, VFD)
It uses frequency conversion technology and microelectronics technology to control the electrical control equipment of AC motor by changing the frequency of motor power supply. . Main inverter rectifier (AC to DC), Filter, inverter (DC-AC)
, Brake unit, drive unit, micro-processing unit, etc.
By destroying the IGBT inverter to adjust the voltage and frequency of the output power, the required power supply voltage is required according to the actual needs of the motor, thereby achieving the purpose of energy saving, the governor, in addition, there are also many drive protection, such as overcurrent, overvoltage, overload, etc.
With the continuous improvement of industrial automation level, frequency converters have been widely used.
The difference between transformer and frequency converter has corresponding technical requirements for different types of transformer technical parameters, and the corresponding technical parameters are expressed.
The main technical parameters of the power transformer are: rated power, voltage ratio rated voltage and rated frequency, temperature level, temperature, voltage ratio, moisture-proof performance and insulation the main technical parameters used for the low-frequency transformer are attributes: voltage ratio, frequency characteristics, nonlinear distortion, magnetic shielding and electrostatic shielding efficiency.
As the name implies, frequency conversion is to change the frequency, that is, the frequency of the motor. The direct view is the speed of the motor. Frequency conversion is like changing the frequency implied by the name, that is, the frequency of the motor, the intuitive point is the speed of the motor.
Transformers are everywhere in our daily life.
Driving Mode: realized by its adjustment to meet the special needs of our power, the power frequency required (50 HZ, 60 HZ, etc).
Transformers: it is common to 'reduce blood pressure' or near plant cells. It is an ultra-high voltage reduced to normal voltage for our residents to meet the daily power consumption of people.
The transformer is a power converter, but compared with the inverter, it can only change the voltage without changing the frequency.
The inverter can not only change the voltage, but also change the frequency to meet the v/f control rule.
