In recent times, the need for energy consumption is drastically increasing to fulfill the global requirements of commercial and domestic consumer demands. Energy generation using conventional methods such as oil and gas are not appreciated in the modern era since they are the major contributors for pollution and global warming. To tackle these issues, energy generation using hybrid renewable energy is being opted and studied universally. However, renewable energy sources have their fair share of drawbacks such as photovoltaic systems rely on the surrounding irradiance and temperature, wind system experiences irregular wind speed, and fuel cells are expensive and less efficient. Also, the energy extracted from renewable sources persist with stochastic behavior. To deal with these issues, researchers utilize different power electronic devices such as inverters, active power filters, voltage regulators, power quality conditioners, and DC-DC converters. Among these power electronic devices DC-DC converters are highly effective for DC voltage regulation and to improve the efficiency of renewable energy systems. Appropriate selection of the DC-DC converter is an important factor that has significant contribution in overall performance of the power systems. Besides, the selection of an efficient DC-DC converter topology, for its optimum operation integration of a suitable control technique is equally important. This paper highlights the characteristics of available and on-going trends of non-isolated converters that includes buck-boost, single ended primary inductor converter, cuk, z-source, zeta, and hybrid DC-DC converters based on the performance parameters that are analyzed using MATLAB Simulink. Control techniques that include proportional integral derivative (PID), slide mode control (SMC), model predictive control (MPC), state space modeling (SSM), and fuzzy logic control (FLC) are also discussed considering the parameters settling issue, response time and complexity while integrating with non-isolated DC-DC converters in power systems.

最近，为了满足商业和国内消费者的全球需求，对能源消耗的需求急剧增加。使用传统方法（如石油和天然气）发电在现代不受重视，因为它们是污染和全球变暖的主要因素。为了解决这些问题，普遍选择和研究使用混合可再生能源发电。然而，可再生能源也有一些缺点，例如光伏系统依赖周围的辐照度和温度，风力系统的风速不规则，燃料电池价格昂贵且效率较低。此外，从可再生能源中提取的能量具有随机行为。为了处理这些问题，研究人员利用不同的电力电子设备，例如逆变器、有源电源滤波器、稳压器、电能质量调节器和 DC-DC 转换器。在这些电力电子设备中，DC-DC 转换器对于直流电压调节和提高可再生能源系统的效率非常有效。正确选择 DC-DC 转换器是一个重要因素，对电源系统的整体性能有显着贡献。此外，选择高效的 DC-DC 转换器拓扑结构，对于其最佳操作集成合适的控制技术同样重要。本文重点介绍了非隔离转换器的可用和持续趋势的特性，包括降压-升压、单端初级电感转换器、cuk、z-source、zeta、和基于使用 MATLAB Simulink 分析的性能参数的混合 DC-DC 转换器。还讨论了包括比例积分微分 (PID)、滑动模式控制 (SMC)、模型预测控制 (MPC)、状态空间建模 (SSM) 和模糊逻辑控制 (FLC) 在内的控制技术，并考虑了参数稳定问题、响应时间与电力系统中的非隔离式 DC-DC 转换器集成时的复杂性。
