The #inverter is a power control device that uses frequency conversion technology and microelectronics technology to control the AC motor by changing the frequency of the motor’s working power supply. The #inverter is mainly composed of rectification (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 switching on and off 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, etc.
Simply put, the #inverter converts DC power (battery, storage battery) into AC power (usually 220V, 50Hz sine wave). Because it is usually used to rectify 220 volts of alternating current into direct current, and the role of the inverter is the opposite, hence the name. In a “mobile” era, mobile office, mobile communication, mobile leisure and entertainment. In the moving state, not only the low-voltage direct current supplied by the battery or the battery is required, but also the 220-volt alternating current which is indispensable in the daily environment. It consists of an inverter bridge, a control logic and a filter circuit. Widely used in air conditioners, home theaters, electric grinding wheels, electric tools, sewing machines, DVDs, VCDs, computers, TVs, washing machines, range hoods, refrigerators, video recorders, massagers, fans, lighting, etc.
The difference between the two is that the #inverter converts DC power (battery, storage battery) into AC power (usually 220V, 50Hz sine wave), and the frequency can also be adjusted; the inverter converts the input AC power into the AC output of the required frequency. ; The principle is “cross-straight-cross” or “cross-cross”, and the form of “cross-straight-cross” is more common. “AC-DC-AC” first converts alternating current to direct current, and then converts direct current to alternating current, that is, “rectification + inverter”
To put it simply, it is actually a different purpose. For example, your home is powered off, but the battery in the electric motorcycle or electric car is very sufficient, so the landlord wants to use the electric energy in the battery to power the computer for Internet access. Need a 220V #inverter. The frequency converter is more used in factory production equipment, and it is a small component in the equipment.
