This device is used to convert Direct Current to Alternate Current. It can be applied in voltage regulation and frequency conversion and generate any AC voltage as the PWM reference input.
A test power energy conversion system is built to drive an induction motor, to study the effect of power on the motor. In order to introduce the harmonics into the power conversion system, a switch model inverter was designed for this system. The simulation results show that the motor speed fluctuates is the motor input voltage has distortion.
