This work presents science can solar system planetary electronic projector w/ 3 viewing discs a partial power converter allowing us to obtain, with a single DC-DC converter, the same feature as the classical interleaved operation of two converters.More precisely, the proposed topology performs similarly as the input-parallel output-series (IPOS) configuration reducing the current ripple at the input of the system and dividing the individual converters power rating, compared to a single converter.The proposed topology consists of a partial DC-DC converter processing only a fraction of the total power, thus allowing high efficiency.Experimental results are provided to validate madelaine chocolate hearts the proposed converter topology with a Flyback-based 100 W test bench with a transformer turns ratio n 1 = n 2.Experimental results show high performances reducing the input current ripple around 30 % , further increasing the conversion efficiency.
