Investigation of PV balancer architectures on practical solar photo voltaic system

Abstract

In this paper, a trending concept of module-integrated converter called as photovoltaic (PV) balancers is presented and verified on a practical data of solar PV system. This concept enables the maximum power point tracking for each module, which historically reduces the requirements for traditional power converters and significant economical impact on overall configuration of solar PV systems. In order to demonstrate the performance of the two possible architectures of PV balancers validated on a practical photovoltaic system and compared with the traditional module integrated converter presented in the literature. Thus, the obtained simulation results with PV balancers are superior in terms of power loss, rating, efficiency, regulation, and voltage stress on switching device.
