Also known as variable frequency drives or drive controllers,Grid tie inverter can be translated Inverter (inverter English). The Grid tie inverter is an adjustable speed drive system (English: Adjustable-speed drive), and the application of variable frequency drive technology change the frequency and amplitude of the voltage of the AC motor work to smooth control AC motor speed and torque, Grid tie inverter the most common input and output are AC AC / AC converter (English: AC / AC converter).
Before the appearance of the Grid tie inverter , adjust the motor speed needs through the DC motor can be completed, or else through the use of built-in coupling machine VS motor operation using coupled machine to decline in the actual speed of the motor, the inverter simplified work out the size of the equipment, a significant reduction in the rate of maintenance. However, the power cord of the Grid tie inverter and the motor line above the high frequency switching signal will cause electromagnetic interference, the power factor of the Grid tie inverter input side is generally poor, will produce harmonics of the power end.
