These drawbacks include the excessive utilization of both passive and active elements, a substantial count of diodes, an increase in the parasitic resistance of inductors and capacitors, and a consequent reduction in efficiency.
Furthermore, the use of only one input capacitor in the MHSLCS eliminates pulsations in the input current at both low and high duty ratios. The proposed converter integrates the MHSLCS with a modified switched capacitor (MSC) that interleaves with the main MOSFET, effectively doubling the voltage transfer gain.
Capacitor C 5 accumulates a significant amount of energy from L 3 and L 4 during the discharging period and supplies high power to the load through D 7.
The addition of a single input capacitor eliminates pulsations in the input current, even at very low duty cycles, enhancing its reliability—especially for photovoltaic applications. Moreover, the diodes in the MHSLCS, namely D 1 and D 2, experience remarkably low voltage stress.
Tantalum and Tantalum Polymer capacitors are suitable for energy storage applications because they are very efficient in achieving high CV.
