English Abstract

Noise can have a negative impact on the performance of dc–dc converters with continuous control set model predictive control (CCS-MPC). This issue is commonly encountered, making it difficult to effectively apply CCS-MPC in dc–dc converters. In this letter, we present a noise tolerance method for dc–dc converters with CCS-MPC that utilizes a virtual capacitor. This method offers a simple and effec...

该研究直接针对DC-DC变换器的控制算法优化,对阳光电源的储能变流器(如PowerTitan、PowerStack系列)及光伏组串式逆变器中的DC-DC级具有重要参考价值。CCS-MPC算法在高性能变换器中应用广泛,但噪声敏感性一直是工程落地的痛点。引入“虚拟电容”策略可有效提升系统在复杂电磁环境下的抗干扰能力,减少对高精度传感器的依赖,从而降低硬件成本并提升产品可靠性。建议研发团队在储能双向DC-DC变换器控制策略中引入该抗噪机制,以优化动态响应性能。
