ABSTRACT
In this paper an integrated hybrid converter topology, unique DC input as well as at same time of outputs DC and AC that use a hybrid control method. At established integrated converter, accomplish high step up voltage and implement outputs of DC as well as AC to greater reliability, switching topology is utilised. The established hybrid strategy is joint execution of spotted hyena optimiser (SHO) and random forest algorithm (RFA), therefore, it called as SHORFA method. In proposed strategy, SHO is utilised to optimise combination of the controller parameters based on the voltage variation. In light of the optimal datasets, the RFA gives the optimal switching pulses of the driver. The RFA learning process is improved to utilise SHO algorithm at aspect of objective function as minimal error. By the established converter design, voltage stress over diodes as well as power switch is lessened. Additionally, the proposed converter directs the output voltage, power factor correction, reduces the voltage spikes over the switches and restrains the switching losses. The proposed strategy performed at worksite of MATLAB/Simulink platform compared to various existing methods.

摘要
在本文中,使用混合控制方法的集成混合转换器拓扑、独特的直流输入以及同时输出直流和交流。在已建立的集成转换器中,实现高升压并实现直流和交流输出以提高可靠性,使用开关拓扑。建立的混合策略是斑点鬣狗优化器(SHO)和随机森林算法(RFA)的联合执行,因此,它被称为SHORFA方法。在所提出的策略中,SHO 用于基于电压变化优化控制器参数的组合。根据最佳数据集,RFA 给出了驱动器的最佳开关脉冲。改进RFA学习过程,在目标函数方面利用SHO算法作为最小误差。通过既定的转换器设计,二极管和电源开关上的电压应力减小。此外,所提出的转换器引导输出电压、功率因数校正、降低开关上的电压尖峰并抑制开关损耗。与各种现有方法相比,所提出的策略在 MATLAB/Simulink 平台的工作现场执行。
