A New Controlled Current Type Inverter with Improved Performance

Three-phase five-level bidirectional buck- + boosttype PFC converter for DC distribution systems

“…4 [3] [10]. These circuits, known as inverting link current source converters, combine a unidirectional six-switch buck-type PFC converter and a voltage and/or current inverting switching section formed by two power transistors and two diodes [9]. Therefore, only 8 power transistors and 8 diodes are required to assemble the converters.…”

Analysis and Control of Torque Pulsations in Current Fed Induction Motor Drives

“…Also the modulation algorithm is much more complex than the simple sine-triangle wave modulation typically used with 358 although the harmonics are problems. Although attempts have been made to program the DC link current in an open loop fashion, such an approach is difficult over a range of load and speed and is subject to the usual deterioration in performance due to parameter changes (3]. This paper describes a different approach to the elimination of torque pulsations in current source induction motor drives by feedback control of the DC link current.…”
