Abstract :
This paper presents a Field Programmable Gate Array (FPGA) based real-time digital simulator for power electronic apparatus based on an realistic device-level behavioral model. A 3-level 12-pulse Voltage Source Converter (VSC) fed induction machine drive is implemented on the FPGA. The VSC model is computed at a fixed time-step of 12.5ns allowing an realistic representation of the IGBT nonlinear switching characteristics and power losses. The simulator also models a squirrel-cage induction machine, a direct field-oriented control system, and a pulse-width modulator to achieve the real-time simulation of the complete drive system. All the models have been implemented using VHDL. Real-time simulation results have been validated using measured device-level IGBT characteristics.
