UAIPD 11-0004: A single Sensor MPPT Controller for Multi-Channel Photovoltaic Solar Systems
A single Sensor MPPT Controller for Multi-Channel Photovoltaic Solar Systems
The controller utilizes an MPPT (Maximum Power Point Tracking) method for a multi-channel PV system that requires only a single sensor compared to 2N (N is the number of channels) sensors required in existing MPPT schemes. Moreover, now adding a new channel will not require adding sensors and requires minor upgrade to an existing system unlike the existing methods where each channel requires a new set of sensors and new controller. This not only results in a smaller, simpler and cheaper renewable energy system, but also extracts higher power and provides the ability to remotely optimize multiple PV solar channels in centralized controller.
