Comparison of a 10 kV SiC Current Switch with two 6.5 kV Series Connected Si SGCTs for Medium Voltage Current Source Inverter Applications
Abstract
Current source inverters (CSIs) are used for various medium voltage (MV) motor drive systems ranging from 100 kWs to MWs. Symmetric gate-commutated thyristors (SGCTs) are used as reverse voltage-blocking (RVB) switches (referred to as a current switch (CS) in this paper) in existing CSI motor drives. However, these devices operate at low switching frequencies (420-720 Hz), leading to bulkier passive components and lower system efficiencies. …
