Higher PV Module Efficiency by a Novel CBS Bypass

There is an increasing focus on reducing costs and improving efficiency for photovoltaic (PV) cells and modules as well as finding a more efficient approach to the product manufacturing. This letter introduces an innovative solution to bypass shaded PV cells instead of a traditional Schottky diode, in order to avoid overheating of cells in the case of partial shading. The goal is to reduce the power dissipation and improve the general efficiency of a PV generator. A novel device called cool bypass switch is then presented. It is made up of a Power MOS driven by a controller with the task to charge a storage capacitor. Tests and comparisons with standard Schottky diodes are then performed an…

DC-DC Converter for Photovoltaic Application with MPPT function embedded interleaved 4

We present a DC-DC converter for photovoltaic (PV) applications that is suitable for a distributed power conversion approach, obtained by transferring part of the electronics from the inverter to the module. The proposed circuit is a high-efficiency four-phase interleaved boost converter employing relatively low-valued inductive and capacitive components. Its realization is made possible thanks to the design of a dedicated integrated circuit (IC) performing the converter control section as well as the Maximum Power Point Tracking (MPPT) algorithm. The solution is designed for a maximum delivered power of 300 W and to work with MPPT voltage between 9 V and 40 V, with maximum allowed panel cu…
