摘要

本文旨在开发一种廉价的自主式光伏阵列灌溉泵，该泵采用开关磁阻电机(SRM)驱动。在光伏阵列和电机泵之间采用改进的Zeta转换器进行功率调节。它的连续传导模式(CCM)操作有助于减少其器件的应力和PV电容器的尺寸。为了使光伏阵列的输出功率最大化，采用了摄动与观测(p&o)最大功率点跟踪(MPPT)控制算法。直流链路电压保持可变，允许减少传感器。中点变换器的基频开关提高了系统的效率。该系统在matlab中进行了预先设计，并通过硬件实现进一步验证。在不同环境条件下的仿真和硬件结果验证了所提出的灌溉泵系统的实用性和价值。

A self-sufficient solar powered SRM driven irrigation pump utilizing modified Zeta converter

This paper aims at developing an inexpensive autonomous photovoltaic (PV) array fed irrigation pump utilizing the switched reluctance motor (SRM) drive. A modified Zeta converter is utilized between PV array and motor-pump to incorporate power conditioning. Its continuous conduction mode (CCM) operation helps to reduce the stress on its devices and also the size of PV capacitor. A Perturb and observe (P &O) maximum power point tracking (MPPT) control algorithm is used to maximize the power output of the PV array. DC link voltage is kept variable which allows reduction of sensors. The fundamental switching of mid-point converter improves the efficiency of the system. The suggested system is premeditated in MATLB and further confirmed with hardware implementation. The simulated and hardware results under varying environmental conditions testify the utility and worthiness of proposed system for irrigation pumps.
