In the solar energy systems the solar irradiance variation is partially engaged, limiting the converter's transformation rate for a certain input amount and leaving the rest of energy unconverted. In order to utilize at its maximum the energy provided from a Photo voltaic (PVP) system, this manuscript proposed a topology that can cope with marginal input voltage variations from 60V(DC) up to 1050V(DC) for a steady output voltage of 700V(DC). This output voltage value is suitable for any interlink post‐regulation architecture. Based on previous observations, this paper presents a wide‐input voltage high‐efficiency non‐isolated single‐control topology. Analysis, operating stages, simulations and experimental results for a 3kW prototype are presented.
