The proposed paper deals with Hardware-In-the-Loop (HIL) validation of a 3-phase PWM boost rectifier controller. This validation has been made using Field Programmable Gate Array (FPGA) target. The development of the Real-Time Emulator (RTE) of the power system is firstly discussed. All voltage sources from the grid, filters, power switches and the load real-time models are implemented in hardware using a Xilinx Spartan-6 FPGA device. As for the controller, a PI-based strategy has been chosen to control the DC-link voltage and a Hysteresis-based one for the control of 3-phase line currents. This controller has been implemented in software using the embedded Cortex-M3 processor of SmartFusion FPGA from MicroSemi. Real-time HIL simulation results, as well as offline simulation results are presented and compared. [ABSTRACT FROM PUBLISHER]

Real-time simulation of Power Electronic Converters (PECs) allows a first realistic validation of their digital controllers and avoids experimental constrains (cost, damage risks, reliability …). However, to increase the realism of validation, the real-time model has to reach a high level of accuracy. This objective is balanced by, among others, the computational time ensured by the used digital technology. This is one of the main reasons why Field Programmable Gate Array (FPGA) devices are preferred. The proposed paper summarizes the hardware FPGA design of PECs real-time model. The Associate Discrete Circuit (ADC) modeling technique is used for each power switch. To make the necessary functional validation, the Matlab/Simulink SimPowerSystems based model has been taken as a reference design. The proposed case study consists of a H-bridge DC-AC converter that supplies an AC load with a sinusoidal back-EMF. The corresponding FPGA-based real-time model is validated at open loop condition and at closed loop with a digital current controller. In addition to functional simulation results, real-time Hardware In the Loop (HIL) simulation results are provided. [ABSTRACT FROM PUBLISHER]

This paper deals with the management of a SoC-based current controller using an efficient Real-Time Operating System (RTOS). To accelerate the services of this operating system, a Real-Time Unit (RTU) was developed in VHDL and associated to the RTOS. It consists in hardware operating system that moves the scheduling and communication process from software RTOS to hardware. Thus, a significant acceleration has been achieved. The experimental tests based on a digital current controller for AC drives were also carried out using a laboratory set-up and a Virtex-5 board. This latter includes a soft-core processor “Microblaze”. The obtained results prove the interest of the proposed approach. [ABSTRACT FROM PUBLISHER]
