Abstract :
The aim of this paper is to present a complete design procedure for a current source converter (CSC) that consists of a PWM current source rectifier (CSR) and inverter (CSI) feeding an induction motor. The procedure includes dimensioning of the input and output filters, as well as the dc-link choke. State-of-the-art SGCT devices are employed in the design and their losses and junction temperatures are calculated. The converter design is made so that the switches in the inverter operate at their maximum specified junction temperature. An example design of a 4.16 kV, 1MW drive is included. Losses of semiconductors and passive components are calculated for different operating points.
