Abstract :
A novel switching control strategy for multi-level (three-level) three-phase dual current source inverters for high power drives applications is reported. The important issue of DC current sharing between the dual inverters is implemented by a simple space vector based PWM scheme for both current source inverters. A second alternative scheme to achieve DC link current sharing using a simple flux-based control is also proposed and implemented by regular sine-triangle PWM scheme. The operation of dual current source inverters is validated under both normal supply voltages, load transients and supply side faults or voltage sags. Detailed simulation results are presented to validate the operation of the dual current source inverter for high power drives applications.
