Design of HIL for Multilevel Inverter Using Zynq-7000 Platform – Part 2
Development of power electronic devices requires multi -disciplined engineering activities. These cover the thermal, electrical and software design. Due to this design complexity rapid prototyping methods and model-based design are becoming more and more important in the R&D projects in this field. This article is the second part of the series which introduces the development of Hardware-in-the-Loop (HIL) device for the simulation of Cellular H-Bridge inverter (CHB). Zynq-7000 platform is chosen as a hardware platform for HIL. This part focuses on the details of the model transformation, development of the hardware environment and the verification of the HIL. FPGA development is also demonstrated including interfaces, IPs and introduction of the resource utilization. Apart from them, operation of the system software in ARM core is also described including TCP/IP interface, IRQ handling and Matlab synchronisation mechanism. Finally, the Matlab interface and simulation results are introduced.
