Pulse converter operating method involves using parallel current inverters in intermediate circuit operated with clock synchronous pulse width modulation to reduce resonance stimulation

摘要

The method involves the use of at least two parallel current inverters in the intermediate circuit and operated with clock synchronous pulse width modulation or PWM to reduce the stimulation of three-phase current and voltage resonances by parasitic impedances. The PWM is controlled so that the sequences of switching states are synchronized according to a fixed pattern within a pulse period.
