This paper investigates the electrical behavior of total cross tied (TCT), SuDoKu (SDK) and killer-SDK (KSDK) configurations under several shading conditions. Three different types of bypass diode (BD) arrangements for these PV arrays (PVAs) have been reported and the considered different BD arrangements are without BD (WBD), non-overlapped BD (NBD) and overlapped BD (OBD). Due to the occurrence of shading situations, the investigation of excess current for various BD based PVA configurations has been carried out. In the present work, maximum prospecting values of excess current for PV modules and arrays are also reported. Moreover, comparative analysis between WBD, NBD and OBD based PVA configurations has been presented using P–V and I–V characteristics. Also, investigation has been extended in terms of reduction of excess current, power dissipation, power improvement, energy savings and earnings. The presented results may be used as a suggestion for appropriate BD interconnection for the chosen PVA configurations. Overall, it is reported in this article that the NBD based KSDK PVA configuration is superior to WBD, OBD and NBD based TCT and SDK PVA configurations.

本文研究了总交叉连接 (TCT)、SuDoKu (SDK) 和killer-SDK (KSDK) 配置在几种阴影条件下的电气行为。已经报道了用于这些 PV 阵列 (PVA) 的三种不同类型的旁路二极管 (BD) 布置，所考虑的不同 BD 布置包括无 BD (WBD)、非重叠 BD (NBD) 和重叠 BD (OBD)。由于阴影情况的发生，已经进行了各种基于 BD 的 PVA 配置的过电流调查。在目前的工作中，还报告了光伏组件和阵列过电流的最大勘探值。此外，基于 WBD、NBD 和 OBD 的 PVA 配置之间的比较分析已经使用P – V和I – V 进行了介绍特征。此外，在减少过电流、功率耗散、功率改进、节能和收益方面的研究也得到了扩展。所呈现的结果可用作对所选 PVA 配置的适当 BD 互连的建议。总体而言，本文报道基于 NBD 的 KSDK PVA 配置优于基于 WBD、OBD 和 NBD 的 TCT 和 SDK PVA 配置。
