Abstract
This thesis proposes an application of photovataic system; that
is, using photovoltaic cell to drive lighting
systems. The stand-alone system not only can be used in
all kinds of operating environment, but
also can help to suppress peak load of utility power so as to
achieve a diversification of energy resources. In this
thesis, maximum power point tracking is analyzed first, and
then, the control strategy and hardware implementation
are proposed. The dimming control methods for electronic
ballast are discussed and compared. One of the dimming control
methods is chosen as reference for designing dimming
electronic ballast. Finally, computer
simulations and hardware measurements are used to verify
the theoretical discussions.
