Abstract
For two PWM inverters for traction purposes phase shifted by 30 degrees and coupled by a three-phase harmonic cancelling reactor the requirements on the control set and its method of operation based on a microprocessor Intel 8086 are described. Starting from a reference space vector (rsv) which represents the needed motor voltages it is shown, how the 6 respective inverter-output-potentials can be calculated in a very short time. Realized are one free running mode for low frequencies and special pulse sequences, which are synchronized with the stator frequency.
