Claim Text:
1. A control system for controlling a DC/DC converter for a photovoltaic panel, the control system comprising: a current estimator for providing an estimated output current of said photovoltaic panel, said current estimator basing said estimated output current on an output voltage of said photovoltaic panel and on a bus voltage of said DC/DC converter; a maximum power point tracker (MPPT) for producing a reference value for an output voltage of said photovoltaic panel, said MPPT receiving said estimated output current from said current estimator; an input voltage controller for producing a desired phase shift for regulating an input voltage of said DC/DC converter, said input voltage controller receiving said reference value from said MPPT; a phase-shift modulator for producing control signals for power switches in said DC/DC converter based on said desired phase shift; wherein said current estimator is based on nonlinear dynamics of said DC/DC converter.
