Design, Implementation and Experimental Analysis of Two-Stage Boost Converter for Grid Connected Photovoltaic System
This paper proposes a two stage boost converter circuit for the grid connected photovoltaic system. Each stage is controlled separately by opposite pulse width modulated signal. Due to nonlinear I-V characteristic of the photovoltaic cells, the converter circuit is designed for the range of input voltage 35 to 60 V, 350V output voltage and maximum output power of 525 watt. Dynamic modeling of the converter is done using state space averaging technique and efficient voltage control topology is suggested. Also operation, principle and performance characteristics of the proposed circuit are discussed and simulated results are validated through practical experiments.
