Abstract This paper presents a new maximum power point tracking control for photovoltaic (PV) panels. The control can be categorized into the Perturb and Observe (P&O) method. It utilizes instantaneous voltage ripples at PV panel output terminals caused by the switching of a chopper connected to the panel in order to identify the direction for the maximum power point (MPP). The tracking for the MPP is achieved by a feedback control of the average terminal voltage of the panel. Appropriate use of the instantaneous and the average values of the PV voltage for the separate purposes enables both the quick transient response and the good convergence with almost no ripples simultaneously.

    Webinar

    As innovation in security and defense technologies increasingly is tied to the commercial sector and as new and non-traditional competitors enter the security and defense space IHS is investigating how new competitors, business models and requirements drive disruption in specific industries, markets and competitive environments. The webinar will present an update on IHS research into a number of issues: How does innovation happen? Are there consistent elements or preconditions for innovation regardless of industry? What are signposts of disruptive innovation? Are there elements of specific industries and markets that will mean that certain constituent elements will be emphasized over others in driving innovation?

    While disruptive technologies, tactics and capabilities may be assessed and evaluated as discrete challenges, the effect of significant shifts in technology can be massively amplified by the convergence of multiple "revolutions" in technology / capabilities / mentalities. These may include revolutions in information, manufacturing, robotics and regional conflicts.
