| Abstract |
The paper presents a new microprocessor-controlled current-source inverter (MCCSI), in which the voltage across the commutating capacitor can be controlled by direct measuring of commutation variables even during the commutation period. In conventional CSI feeding the inductive load such as an induction motor, the voltage across the commutating capacitor depends on the capacitance of the commutating capacitors and the external load condition. In the proposed inverter, the peak capacitor voltage can be controlled according to the link current. So the commutation capability is not lost under fast change of the DC link current or load condition. In this paper the operating principle and experimental results of the new MCCSI are described. The operation with other drive systems such as double fed machine and synchronous machine is discussed. It is shown that the inverter is suitable for AC drives, it has no load depending
