    CM Buck Project
    (2024-05-02) Boone, Sam; Gonzalez, Anthony; Freije, Elizabeth; Pash, Phillip
    For this project, we are looking at a more cost-effective alternative to the Modbus to BACnet converters that are being used with the critical power equipment our company sells. These converters will be used in places where the existing building management systems use BACnet communication protocols. The current converters are over-engineered and overly complex for our customers’ needs who are requesting a simplified option. Our design needs to be able to monitor multiple pieces of critical power equipment, as well as have ride through time in the event of power loss to provide continuous monitoring.

    PV Based Converter with Integrated Battery Charger for DC Micro-Grid Applications
    (2014) Salve, Rima; Santos Jr., Euzeli C. dos
    This thesis presents a converter topology for photovoltaic panels. This topology minimizes the number of switching devices used, thereby reducing power losses that arise from high frequency switching operations. The control strategy is implemented using a simple micro-controller that implements the proportional plus integral control. All the control loops are closed feedback loops hence minimizing error instantaneously and adjusting efficiently to system variations. The energy management between three components, namely, the photovoltaic panel, a battery and a DC link for a microgrid, is shown distributed over three modes. These modes are dependent on the irradiance from the sunlight. All three modes are simulated. The maximum power point tracking of the system plays a crucial role in this configuration, as it is one of the main challenges tackled by the control system. Various methods of MPPT are discussed, and the Perturb and Observe method is employed and is described in detail. Experimental results are shown for the maximum power point tracking of this system with a scaled down version of the panel's actual capability.
