“…Conversely, we used multiplex testing methods to improve the quality of products. We all know that zero-defect high-quality products (Zero Defect Manufacturing, ZDM) [20,21] are the ultimate goal of all industries. The quality requirements in the biomedical or automotive electronics industries are stringent, with higher safety requirements.…”

“…Various work can be found in the literature taking advantage of both standalone FP-GAs [11][12][13][14][15] and Zynq SoCs [10,[16][17][18][19][20][21][22][23][24][25] to control power electronics devices. Most presented Zynq-based solutions use development boards for prototyping [10,17,[19][20][21][22]24,25], including the Zedboard used in this paper [10,[19][20][21]24]. A custom hardware platform is proposed in [17] specifically for power electronics control.…”

“…Many FPGA-based solutions found on the literature rely on conventional low-level coding (typically using HDL and C on Xilinx tools) [16,17,20,21,23]. Other solutions use the Xilinx System Generator toolbox in Matlab/Simulink, to enable model-based design [19,24].…”

Many advanced power electronics control techniques present a steep computational load, demanding advanced controllers, such as FPGAs. However, FPGA development is a daunting and time-consuming task, inaccessible to most users. This paper proposes a complete methodology for prototyping power electronics with Xilinx Zynq-based boards using Matlab/Simulink and HDL Coder. Even though these tools are relatively well documented, and several works in the literature have used them, a methodology for developing power electronics systems with them has never been proposed. This paper aims to address that, by proposing a complete programming and design methodology for Zynq-based power electronics and discussing important drawbacks and hurdles in Simulink/HDL Coder development, as well as their possible solutions. In addition, techniques for the implementation of all required peripherals (ADCs, digital outputs, etc.), system protections, and real-time data acquisition on Zynq boards are presented. This methodology considerably reduces the development time and effort of power electronics solutions using Zynq-based boards. In addition, a demonstration Simulink model is provided with all proposed techniques and protections, for use with a readily available development board (Zedboard) and ADC modules. This should further reduce the learning curve and development effort of this type of solution, contributing to a broader access to high-performance control prototyping using Zynq-based platforms. An application example is presented to demonstrate the potential of the proposed workflow, using a Zedboard to control a multilevel UPS inverter prototype with Model Predictive Control.

“…The vast number of inputs-outputs (IOs) in the FPGA allows designers to generate several and various numbers of gating signals, since in microcontrollers the number of PWM signals and their timings are limited. In this work, the SoC platform for power electronic applications is introduced and published in [38] and also implemented for the verification of the detection algorithm introduced in Chapter 4. The methodology used in this novel solution is explained and experimental results are presented.…”

Real-Time Fault Detection and Reconfiguration of a Three-Phase Electric Motor Drive

Variable-frequency drives (VFDs) are widely used for control of electrical machines such as induction motors (IMs) or permanent-magnet synchronous motors (PMSMs). Similar to other electrical devices, these drives are subject to failure. Several types of faults are associated with VFDs. For instance, faults such as open-switch faults, and short-circuit switch faults are the two common faults in VFDs. These faults can yield catastrophic consequences if proper remedial action is not taken. A unique remedial topology for the post-fault period and a new pulse width modulation (PWM) strategy are proposed so that not only the motor drive can continue the operation, but also this new method reduces the common-mode voltage of the three-phase inverter. In this work, switch failures are investigated, and a new solution to detect openswitch faults are proposed using an algorithm based on current analyses. Extensive simulations are done to simulate a real system response during the post-fault phase on different operating points and at various torque loads. These simulation results were used to develop a detection algorithm. These results were also verified using an experimental setup. The proposed method offers an efficient solution for fault detection in VFDs. First, a fast response detection of a failure in an inverter is possible. Second, it provides an alternative back-up method for fault detection in electric drive systems. v
