The FPGA (Field Programmable Gate Array) implementation of real-time Hardware-In-the-Loop techniques is constantly growing due to its high speed. However, hardware implementation of SMPS (Switched-Mode Power Supplies) introduces some challenges, because their equations are changed depending on the state of the switches. This becomes more important in multistep numerical methods, which use several previous values. This letter presents the implementation scheme of Adams-Bashforth method which allows the designer to correctly apply it to switching power converters. The global accuracy and utilization results of the approach are analyzed in the letter. The results show that the proposed modification makes sense due to the high accuracy improvement at the expense of a reasonable increase in resources.

用于开关转换器实时仿真的 Adams-Bashforth 方法中重置存储器的必要性

由于其高速，实时硬件在环技术的 FPGA（现场可编程门阵列）实现不断增长。然而，SMPS（开关模式电源）的硬件实现带来了一些挑战，因为它们的方程式会根据开关的状态而改变。这在使用多个先前值的多步数值方法中变得更加重要。这封信介绍了 Adams-Bashforth 方法的实现方案，该方法允许设计人员将其正确应用于开关电源转换器。信中分析了该方法的全局准确性和使用结果。结果表明，由于以资源的合理增加为代价提高了准确性，因此所提出的修改是有意义的。
