Variable size Dynamic PV array for small and various DC loads

This paper proposes to operate different DC voltage rated loads individually using a Dynamic PV array (DPVA). This paper proposes a general procedure to design a specific size DPVA for producing a unique number of configurations. Hereafter, each DPVA is assigned a unique number to distinguish from others. Further, this paper derives a mathematical relation of the DPVA size and the least output power (LOP) it can produce at all load and irradiance conditions. Validating the derived LOP limit, Simulation tests of four different DPVAs have been conducted. Further, a six-module PV array-based experiments consisting a double pole double throw (DPDT) switch-network and a resistive load have been conducted. Results have validated the smooth working of the proposed DPVA at all irradiance and load conditions.
