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 <italic xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">R</i><sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">on</sub>/<italic xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">R</i><sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">off</sub> 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.
