This paper focuses on the design of multi-structure controllers (MSCs) for KY negative output boost converter (KYNOBC) functioned in continuous current mode (CCM) for low-power source applications. KYNOBC is one of the topologies of DC–DC converter that performs the positive DC input supply voltage into a negative output voltage. Dynamic behavior of KYNOBC is nonlinear in nature because of its time-changing operation. The single loop control does not regulate the multi-parameters of KYNOBC during the line and load variations owing to that it produces poor transient and dynamic analyses. With the aim of controlling the multi-parameters of KYNOBC such as inductor current and output voltage, enriching the transient and dynamic analysis, the MSCs are recommended in this paper. In our study, MSCs for KYNOBC consist of two loops such as inner proportional (P) controller inductor current loop for modulating the converter current and outer fuzzy logic controller (FLC)/proportional integral (PI) controller voltage loop for regulating the output voltage. The P and PI values are determined from the mathematical modeling of KYNOBC and the fuzzy rules are framed based on its performance without modeling equations. The behaviors of the KYNOBC with MSCs are validated at various zones by making the MATLAB/Simulink simulations and prototype model. The controller parameters are realized in prototype field programmable gate array (FPGA). The responses are recorded to indicate the dexterous of the MSCs for it.

KY负输出升压转换器有效多结构控制器的性能评估

本文重点介绍了 KY 负输出升压转换器 (KYNOBC) 的多结构控制器 (MSC) 设计，该转换器在连续电流模式 (CCM) 下运行，适用于低功率电源应用。KYNOBC 是 DC-DC 转换器的拓扑结构之一，可将正 DC 输入电源电压转换为负输出电压。KYNOBC 的动态行为本质上是非线性的，因为它是随时间变化的操作。单回路控制不会在线路和负载变化期间调节 KYNOBC 的多参数，因为它会产生较差的瞬态和动态分析。为了控制KYNOBC的电感电流和输出电压等多参数，丰富瞬态和动态分析，本文推荐使用MSC。在我们的研究中，用于 KYNOBC 的 MSC 由两个回路组成，例如用于调制转换器电流的内部比例 (P) 控制器电感电流回路和用于调节输出电压的外部模糊逻辑控制器 (FLC)/比例积分 (PI) 控制器电压回路。P 和 PI 值由 KYNOBC 的数学建模确定，并且基于其性能构建模糊规则，无需建模方程。通过制作 MATLAB/Simulink 仿真和原型模型，在各个区域验证了带有 MSC 的 KYNOBC 的行为。控制器参数在原型现场可编程门阵列（FPGA）中实现。记录响应以指示 MSC 的灵巧性。
