摘要

提出了一种开关电容降压-升压DC-DC变换器，用于采用开关磁阻电机驱动的SPV (Solar Photovoltaic)水泵系统。SRM驱动的速度是通过改变中点转换器的直流链路电压来调节的，这取决于日照水平。此外，SRM驱动采用基本开关操作，这有助于最小化中点变换器的开关损耗，并提高所提出的水泵系统的效率。为了降低电感的振铃效应和开关电容buck-boost变换器参数的应力，将开关电容buck-boost变换器工作在连续导通模式下。仿真结果表明，该系统在各种可能的环境条件下均能高效运行。

SPV array powered SC buck-boost converter fed SRM drive for water pumping

A switched capacitor buck-boost DC-DC converter is proposed for SPV (Solar Photovoltaic) powered water pumping system employing SRM (Switched Reluctance Motor) drive. The speed of SRM drive is regulated by changing the DC link voltage of a mid-point converter which depends upon the insolation levels. Moreover, the SRM drive is operated with fundamental switching which helps to minimized switching losses in a mid-point converter and increases the efficiency of proposed water pumping system. A switched capacitor buck-boost converter is operated in continuous conduction mode (CCM) to lowering the ringing effect of inductors and stress on switched capacitor buck-boost converter parameters. From the analysis of simulated performance of proposed system, it is revealed that the system operates efficiently at all possible environment conditions.
