A portable, modular, plug-and-play photovoltaic (PV) converter system is proposed in this paper. Each PV subpanel has an individual DC/DC converter connected in parallel to a semi-regulated DC bus. In order to accommodate diverse loads, a distributed control strategy for each converter is utilized so that the PV subpanel can operate at either Maximum Power Point Tracking (MPPT) mode or power shedding...
In photovoltaic applications, a high step-up dc/dc converter is required to serve as the power electronic interface between the low voltage solar panel and the high voltage dc bus. In this paper, a novel high step-up dc/dc converter is proposed to enhance the performance of voltage converting. The proposed converter is based on a coupled inductor, and integrates synchronized boost topology and switch...
In this paper, a high power density single-phase inverter for photovoltaic system is presented. The proposed converter consists of a resonance-type isolated DC/DC converter, a power decoupling circuit and a current source inverter (CSI). In particular, the volume reduction of capacitors and inductors is focused. Consequently, a leakage inductor of a center-tapped transformer is used as a DC inductor...
The problem of ever-increasing energy demand and depletion of conventional resources is well known. In order to meet this growing demand, residential rooftop Photovoltaic (PV) systems, which can cater to the household demand and also supply excess power to the grid, are being encouraged. In this paper, a two-stage transformerless single-phase grid-tied PV system for residential rooftop application...
