摘要

本文的主要目标是开发一种电力调节系统,该系统可以从太阳中提取可变的太阳能直流电,并将其转换为交流电源,有效地为三相交流负荷供电。本文给出了三相交流负荷下光伏电力调节系统的仿真结果。该调节器由二极管箝位的三电平逆变器组成,由闭环压控DC-DC升压转换器供电。在占空比控制方法中,采用传统的脉宽调制器(PWM)实现DC-DC变换器的闭环控制。该升压变换器设计用于从可变太阳能中获得可调节电压。在FPGA上采用移电平正弦PWM控制多电平逆变器。

Power conditioning system for solar power applications: Closed loop DC-DC convertor fed FPGA controlled diode clamped multilevel inverter
The main objective of this paper is to develop a power conditioning system, which can be used to extract the variable solar DC power from sun and convert it into AC power to feed a 3-phase AC load effectively. This paper presented the simulation results of Photovoltaic (PV) power conditioning system for three phase AC loads. The conditioner consists of a diode clamped three level inverter fed by closed loop voltage controlled DC-DC Boost converter. This closed loop control of DC-DC converter is implemented by a conventional Pulse Width Modulator (PWM) in duty cycle ratio control method. This boost converter is designed to obtain regulated voltage from the variable solar power. A level shift sinusoidal PWM is used to control the multilevel inverter on FPGA.
