Recent developments in power electronics technologies have resulted in a need for fast responses and dynamic control. However, existing control schemes are still limited to the available digital signal processors (DSPs) and their associated high prices. The field-programmable gate array (FPGA) offers fast performance and high control flexibility by providing a reconfigurable computing speed. However, it has some implementation limitations in standalone systems. In this regard, this paper presents a hardware setup for a three-level hybrid active neutral point inverter (HANPC) using a FPGA and a DSP. A unique method using digital and analog modulation is designed in this study using Vivado software. The proposed method depends on receiving analog reference signals from the DSP and then performing all the required processes using the FPGA. Direct pulse width modulation is generated to control the HANPC without changing the hardware configuration of the main topology. The implemented hardware is based on a 15 kW HANPC topology that is mainly controlled by a Digilent Zybo-Z7-20 FPGA. The effectiveness of the proposed system was verified by experimental results.

电力电子技术的最新发展导致需要快速响应和动态控制。然而，现有的控制方案仍然局限于可用的数字信号处理器 (DSP) 及其相关的高昂价格。现场可编程门阵列 (FPGA) 通过提供可重新配置的计算速度来提供快速的性能和高度的控制灵活性。但是，它在独立系统中存在一些实现限制。在这方面，本文介绍了使用 FPGA 和 DSP 的三电平混合有源中性点逆变器 (HANPC) 的硬件设置。本研究使用 Vivado 软件设计了一种使用数字和模拟调制的独特方法。所提出的方法依赖于从 DSP 接收模拟参考信号，然后使用 FPGA 执行所有所需的过程。生成直接脉宽调制以控制 HANPC，而无需更改主拓扑的硬件配置。实现的硬件基于 15 kW HANPC 拓扑，主要由 Digilent Zybo-Z7-20 FPGA 控制。实验结果验证了所提出系统的有效性。
