Analysis of analog MPPT Algorithms for Low cost Photovoltaic System

저가형 태양광 발전시스템을 위한 아날로그 MPPT 알고리즘의 특성 해석

In this paper, Simple and inexpensive analog maximum power point tracker (MPPT) algorithm for photovoltaic power system and low power system of doesn't use digital signal processor (DSP). The control circuit is composed such that the actual current and voltage are sensed directly from the PV array. These two signals are then multiplied by a single-chip multiplier. The multiplier output go through different time constants genesis pulse width modulated to switch. Finally those were verified through simulation.
