Abstract
Current control in voltage-source inverters with random pulsewidth mod ulation (RPWM) is investigated. The random modulation is introduced to alleviate the undesirable acoustic, vibration, and EMI effects in inv erter-fed ac drive systems. A novel RPWM digital technique with dither ing of the switching frequency and compensation of the processing time is described. Design of the current control loop is discussed. Result s of investigation of an experimental drive system are presented, prov ing the feasibility of the proposed solutions.
