EMHEATER Inverters

The frequency converter – electronic device for changing the frequency of the current (voltage). It converts the input sinusoidal voltage of fixed frequency and amplitude of the starting pulse voltage of variable frequency and amplitude by means of PWM (Pulse Width Modulation) .Such way gradually increasing the frequency and amplitude of voltage supplied to the stator windings of the induction motor, it is possible to ensure a smooth speed control the motor shaft.
