Many customers will be confused about power inverter and frequency inverter, sometimes when Person ask what is the “inverter” , here inverter have many word group, which exactly it is?Now I want to simply introduce the power inverter and frequency inverter.
Firstly what is the frequency inverter.
Frequency converter is the voltage provided by the voltage constant voltage conversion into voltage and frequency can be changed through the control of the converter, so that the motor can be driven by the power supply voltage to play a better work performance.
Frequency converter is the Chinese translation of VFD / VVVF, frequency converter is the use of power semiconductor devices on-off effect of frequency power supply into another frequency of energy control device.
The role of the inverter is to change the AC motor power supply frequency and amplitude, and thus change the movement of the magnetic field cycle to achieve the purpose of controlling the motor speed.
The working principle of the frequency converter is to rectify the power frequency rectifier into direct current through the rectifier bridge, and then use the inverter composed of semiconductor devices to convert the direct current into variable voltage and variable frequency alternating current for driving the induction motor, Speed regulation. The above two changes can be simplified to AC-DC-AC (AC-DC-AC).
Its energy-saving mainly in the fan, water pump applications. In order to ensure the reliability of production, a variety of production machinery in the design with power-driven, have left a certain amount of margin. The role of the motor drive is to speed, and reduce the starting current.
Secondly what is power inverter
Power Inverter is the DC power (battery) into alternating current (usually 220V, 50Hz sine wave) for general electrical use, is a convenient power converter. It consists of inverter bridge, control logic and filter circuit.
Widely used in air conditioning, home theater, electric wheel, power tools, sewing machines, DVD, VCD, computers, television, washing machines, range hoods, refrigerators, video recorders, massagers, fans, lighting. In foreign countries because of the high penetration of the car to go out to work or travel can be used to connect the inverter battery charger and a variety of electrical tools to work. The car inverter output through the cigarette lighter is 20W, 40W, 80W, 120W to 150W power specifications. And then a large number of power inverter power through the cable connected to the battery. By connecting the appliance to the output of the power converter, various appliances can be used in the automobile. You can use the electrical appliances are: mobile phones, notebook computers, digital cameras, cameras, lights, electric shavers, CD players, games, handheld computers, power tools, car refrigerator and a variety of tourism, camping, medical emergency electrical and so on.
In one word, frequency Inverter is AC – DC – AC, power inverter is DC – AC, frequency inverter can change the frequency also, and the power inverter as long as the fixed output frequency on the line
