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 functions of single to three phase frequency inverter
- Frequency conversion energy saving
The frequency conversion energy saving is mainly performance in the applications of fan and water pump. All kinds of production machineries in the design with power drive have a certain amount of surplus in order to promise the reliability of production. When the motor cannot run at full load, the excess torque increases the consumption of active power, which causes the waste of electric energy. The speed control method of fan, water pump and other equipment is by adjusting the inlet or outlet baffle, valve opening to get the amount of air and water, the input power is large and a large amount of energy is consumed during the closure of the baffle and valve. When you use the single to three phase frequency inverter to control speed, if the flow is required to be reduced, you can reduce the speed of the fan and water pump to meet this requirement. The function of the frequency converter used in the motor is speed control and Reduction of starting current. - Power factor compensation energy saving
Reactive power not only increases the line loss and the heating of equipment, but also leads to the reduction of the active power of the grid. Large reactive energy consumption in the line will cause low efficiency of equipment use and serious waste. After the use of single to three phase frequency inverter, due to the function of the filter capacitor inside it, the reactive power loss is reduced and the active power of the power grid is increased. - Soft start energy saving
The hard start of the motor will cause serious impact on the power grid, and it will also require too much capacity of the power grid. The large current and vibration generated during the motor start will cause great damage to the baffle and valve, which is extremely detrimental to the service life of equipment and pipelines. After using the frequency inverter, the soft start function of it will make the current start from zero, the maximum value will not exceed the rated current, so as to reduce the impact on the power grid and the demand for power supply capacity. This will prolong the service life of the equipment and valve and save the maintenance cost.
