A maximum power point control scheme applied to a noncascading dc-dc converter for a PV system

Abstract

A maximum power point tracking (MPPT) scheme based on a general pulse width modulation (PWM) modulator is presented. The purpose of the scheme is that switching converter behaves as a resistor seen by the photovoltaic module, it also regulates the input voltage to a desired value. The MPPT scheme is applied to a noncascading converter topology, which has the characteristic of processing a fraction of the total power generated.
