中文摘要
本文设计了一种非隔离式混合无桥双输出（NHBLDO）变换器，用于电机驱动，并提升单相电网供电的开关磁阻电机（SRM）的电能质量。根据中点变换器（MPC）辅助的开关磁阻电机驱动需求，通过集成Zeta变换器和规范开关单元（CSC）变换器，开发了一种带中点的NHBLDO前端变换器。该变换器设计为在不连续电流模式（DCM）下运行，适用于低功率、低成本应用。此外，单电压控制器中使用的单个电压传感器足以满足要求，且易于在低成本、低功率电器中实现。开发了具有双输出的非隔离式混合无桥变换器（NHB变换器），以补偿电网电压变化，并调节分裂电容电压，从而实现开关磁阻电机驱动的宽速度控制。此外，所选的NHBLDO变换器组件在500 W额定功率下能实现令人满意的性能。本文详细讨论了理论分析和工作模式。最后，通过仿真验证了所提出的由NHBLDO变换器供电的开关磁阻电机驱动，并通过在220 V、500 W、300 V直流母线电压下运行的实验室装置进行了验证。结果显示，该驱动效率达93.23%，输入功率因数为0.993，电流总谐波畸变率（THD）约为3.70%，符合国际电工委员会（IEC）61000 - 3 - 2标准的推荐要求。
English Abstract
A non-isolated hybrid bridgeless dual output (NHBLDO) converter is designed for motor drive along with power quality enhancement of single-phase grid fed switched reluctance motor (SRM). A NHBLDO front end converter with mid-point is developed by integrating Zeta and canonical switching cell (CSC) converter as per requirement of mid-point converter (MPC) assisted SRM drive. This converter is designed to operate in discontinuous current mode (DCM), which is suitable for low power low-cost applications. Moreover, single voltage sensor used in single voltage controller is sufficient and easy to implement for low-cost low power appliances. Non isolated hybrid bridgeless converter with dual output NHB converter is developed to compensate for grid voltage variations ranging along with split capacitor voltage regulation for wide speed control of SRM drive. Moreover, NHBLDO converter components are selected to perform satisfactorily for 500 W power rating. Theoretical analysis and operating modes are discussed in detail. Finally, presented NHBLDO converter fed SRM drive is verified through simulation and validated through laboratory setup operating at 220V, 500-W, and 300V DC link voltage, yielding 93.23% efficiency, 0.993 input power factor, and around 3.70% current THD, which is as per recommended IEC 61000-3-2 guidelines.
