Abstract

This study proposes a new circuit consisting of a high voltage gain DC-DC Boost converter and a single phase two stage inverter for PV cell system. The DC-DC boost converter topology achieves high voltage gain by coupling inductors and the voltage lift technique. The inverter consists with a combination of sinusoidal pulse width modulation (SPWM) and a square wave along with grid synchronization condition. The simulation work of this circuit has been done using PSIM. The new conversion technique revealed the low ripple, low THD below 0.1%, low cost and simple control.

光伏电池系统高效转换方法的设计与研究

本文提出了一种由高压增益DC-DC升压变换器和单相两级逆变器组成的新型光伏电池系统电路。DC-DC升压变换器拓扑结构通过电感耦合和电压提升技术实现高电压增益。该逆变器由正弦波脉宽调制(SPWM)和方波调制组合而成，并随电网同步条件变化。利用PSIM软件对该电路进行了仿真。该转换技术具有低纹波、低THD低于0.1%、成本低、控制简单等特点。
