This paper proposes an input-series-output-parallel connected ZVS full bridge converter with interleaved control for photovoltaic power conditioning systems (PV PCS). The input-series connection enables a fully modular power-system architecture, where low voltage and standard power modules can be connected in any combination at the input and/or at the output, to realize any given specifications...

Distributed energy resources (DERs) and microgrids have seen tremendous growth research activities in recent years. Flexible DERs asynchronous (ASMG) can many system-level benefits over fixed conventional microgrids. The key enabler for flexible ASMG is a power converter based conditioning system (PCS) as the interface between DERs/microgrids medium voltage (MV) distribution grid. High (HV, &#x...

This paper proposes a second-order harmonic reduction technique using a proportional-resonant (PR) controller for a photovoltaic (PV) power conditioning system (PCS). In a grid-connected single-phase system, inverters create a second-order harmonic at twice the fundamental frequency. A ripple component unsettles the operating points of the PV array and deteriorates the operation of the maximum ...
