SIMULATION OF THE OUTPUT STAGE OF THE FREQUENCY CONVERTER

The transistors are switched from one state to another jump, and then the output voltage will have a stepped shape. For some devices this form of the output voltage is acceptable, but this is absolutely not a form suitable for powering electric motors. In order to be able to connect to such a frequency converter motor, it is necessary after the bridge inverter supply filtr.Osnovnaya filter problem - it's smooth shape of the curve at the output of the bridge inverter, ie, obtained from step input signal sinusoidally varying voltage at the filter output.
