The proposed topology comprises five switches and a common core coupled inductor that uses only a set of complementary pulse-width-modulated signals to control and achieve high voltage gain without requiring high turn ratios or excessive duty cycles.
The tests were conducted under different input and load conditions to verify that the converter has stable output characteristics. In addition, the proposed converter has low input current ripple, high voltage gain, low switching stress, and common ground characteristics, which makes it suitable for integrated multi-energy storage systems.
Coupled inductors have been incorporated into DC–DC nonisolated converters to increase the voltage gain of these converters [ 22, 23, 24 ]. Switches with zero-voltage switching (ZVS) can increase the conversion efficiency; however, a higher number of circuit components increases the cost of a converter [ 22, 24 ].
In 22, a switched inductor technique is utilized to construct a high step-up boost converter with fewer components and a simple structure, but the voltage gain is significantly reduced at low voltage inputs with low efficiency due to the hard-switching work condition.
Another study used a three-winding coupled inductor and a half-wave voltage doubler to increase the voltage gain and lower the components of the circuit; however, the turns ratio of coupled inductor is high, which causes larger volume of the circuit [ 30 ].
The energy stored in L1 charges C1, inductor L2 charges capacitor C2, and provides energy to capacitors Co1, Co3, and Co4 through output diode Do1. At the same time, the coupled inductor N1 transfers energy to N2, and the energy in N2 transfers energy to capacitor Co2 and the load together with capacitors Co3 and Co4.
