Real-Time Simulation Method for Power Electronic Converters With Low Resource Consumption

This letter presents a real-time simulation method for bridge-based power electronic converters based on the R_on/R_off model. By constructing the equivalent system state equation, all multiplications can be performed by shift addition operations in field programmable gate array (FPGA) implementation and avoids using limited multipliers. Then, a 50-kHz dual active bridge converter and a 100-kHz ac-dc–ac converter are simulated on FPGA with 20 ns simulation time step. Accuracy, timing, and resource consumption results verify the effectiveness of this method.
