Three phase frequency inverter, also named as 3 phase variable frequency drive (VFD), is a motor control with 3 phase input and output that drives motor by changing the frequency and voltage supplied to the motor. The frequency is directly related to the rotary speed of the motor, in other words, the faster the frequency, the faster the rotary speed. If the motor is no need to run at full speed, the frequency inverter can be used to reduce frequency and voltage to meet the requirement of motor load.
Single phase output frequency inverter, also called 1 phase variable frequency drive or VFD, is a power control equipment that adopts frequency conversion technology and microelectronic technology to control the AC induction motor by changing its working power frequency. Frequency inverter is mainly composed of rectifier (AC to DC), filter, inverter (DC to AC), brake unit, drive unit, detection unit and micro-processing unit. It relies on internal IGBT disconnection to adjust output power supply voltage and frequency and provide the required power supply voltage according to the actual requirements of the motor, so as to realize speed regulation and energy saving. In addition, the frequency inverter has many protection functions, such as overcurrent, overvoltage and overload protection. With the continuous improvement of industrial automation, the frequency inverter have also been very widely used.
Single to three phase frequency inverter is a motor control with single phase input and three phase output, which is mainly used for speed control of 3 phase AC induction motor on 1 phase power supply. Frequency inverter, as known as variable frequency drive (short for VFD), has lots of functions and operation ability. For example, it provides phase supply protection, undervoltage protection and overvoltage protection for motors.
The sine wave inverter is a kind of inverter that direct current into alternating current. It is widely used for air conditioning, television, water heater, LED light, printer, computer system, communication system, aviation, emergency, industrial equipment and communication equipment, etc. The pure sine wave inverter can also be used in places where emergency backup power is required, which can constitute EPS emergency power supply system. The output waveform of the sine wave inverter is a complete sine wave with low distortion rate, therefore, it is low noise and high efficiency.
On grid inverter or grid tie inverter from Inverter.com, can convert direct current into alternating current. Its AC output can synchronize with the frequency and phase of mains supply. On grid inverters are commonly used in applications where direct current voltage sources are connected to the grid, such as solar panels and small wind turbines. The output voltage frequency of the solar grid tie inverter needs to be same as the grid frequency (50 Hz or 60 Hz). A MPU in the grid tie inverter can sense the AC waveform of the power grid and generate voltage back to the power grid based on the waveform.

Different voltage power inverter have different prices. Power inverter is a device that can convert DC (the battery and accumulator jar) into AC (normally the sinusoidal wave of 220V and 50Hz). It is composed of inverter bridge, control logic and filter circuit. With a power inverter, direct current (battery, switching power supply, fuel cell, etc.) can be converted into alternating current to provide stable and reliable power protection for electrical appliances, such as laptops, mobile phones, handheld PCs, digital cameras, and various instruments. Inverters can also be used with generators, which can effectively save fuel and reduce noise. The power inverter has a wide range of uses. It can be used in various vehicles, such as automobiles, ships and aircraft.
