The Electrical Drive Systems with the Current Source Converter

The chapter presents two approaches to the control of electric machines supplied by the current source inverter. The first one is based on the current control and the second contains the voltage control which uses the multi‐scalar variables. In the voltage control the current source inverter is treated as the commutator of the current in dc‐link to the ac machine stator current. The dc‐link current is proportional to module of the stator current. The inverter works in the constant modulation index, so the transistors conduction power losses can be limited. The multi‐scalar voltage approach is applied to the squire‐cage, doubly fed induction machine and the permanent magnet synchronous machine. All the mathematical investigations are supported by the simulation and experimental tests.
