FPGA-Based Hardware-in-the-Loop Simulation for Resonant Converters

 

(Download)

In the field of mechatronics and electrical drives hardware-in-the-loop (HiL) simulation is one the commonly used tool for controller development and test. Different to an algorithm-level or software-level simulation in offline mode, using a HiL simulator the whole controller (incl. hardware and software) can be tested in physical signal level.

However, due to the hardware limitation a conventional digital processor-based HiL simulator has a relative long simulation step-size from 10 µs to some 10 µs, which means limits its application in higher switching frequency-operated DC-DC converters. Thanks the parallel processing ability a much shorter simulation step-size of some ten nanoseconds can be achieved by using field-programmable gate array (FPGA) technology.

Within this work real-time simulation models for a series-parallel resonant converter with LC (SPRC-LC) output filter shall be developed and implemented in FPGA hardware. In details:
