Question:

What is the difference between inverters and inverters?!!

Today, I was asked the question, and I also brought it to you to share the following Oh!

Answer:

Inverter inside the circuit is inverterIt is a control of communication -- direct current -- CommunicationDC alternating current is called inverter
The frequency converter is the electric energy control device that transforms the power frequency power to another frequency by the on-off function of the power semiconductor device. We now use the converter mainly adopts the AC-DC-AC mode (VVVF inverter or variable frequency vector control), the first AC power into DC power supply through the rectifier, then the AC power into DC power supply frequency and voltage can be controlled by the supply of electric motive. The frequency converter circuit is usually composed of rectifier, intermediate DC link, inverter and control of 4 parts. The rectifier is a three-phase bridge controlled rectifier, and the inverter is IGBT three-phase bridge inverter, and the output is PWM waveform. The intermediate DC link is filter, DC energy storage and buffer reactive power.
The inverter (power converter, Power Inverter) is a kind of DC12V can be converted to DC and AC220V AC power the same, for general use of electrical appliances, power converter with a convenient car.
The frequency of the electricity we use everyday is 50Hz. If we want to change the frequency, we have to change it through the frequency converter.The working principle of frequency converter is to change the frequency alternating current into no frequency direct current, and then control it by electronic circuit so that it can adjust its frequency alternating current at any time.The inverter is similar to the back half of the inverter, which converts the direct current into alternating current.
