An Advanced Current-Auto-Balance High-Step-Up Converter with a Multi-Coupled Inductor and Voltage Multiplier for a Renewable Power Generation System

Interleaved High Step-Up DC-DC Converter Based on Voltage Multiplier Cell and Voltage-Stacking Techniques for Renewable Energy Applications †

“…The performance comparison between the converters published in [20][21][22] and the proposed converter is shown in Table 1. The relationship between the voltage gain and the duty ratio in these converters with the turns ratio n = 1.5 is shown in Figure 7.…”

“…The experimental results shown in the Figures 8-15 are measured under full-load conditions 1000 W. [20] and [22] Converter in [21] Proposed converter …”

“…In the literature, a lot of converter topologies have been proposed to obtain high step-up voltage gain [6][7][8][9][10][11][12][13][14][15][16][17][18][19][20][21][22]. For coupled inductor-based converters [6][7][8][9][10], the high voltage gain can be achieved by adjusting the turns ratio of the coupled inductor and duty ratio.…”

“…Several kinds of interleaved high step-up converters with voltage multiplier cells have been proposed in [15][16][17][18][19]. The interleaved converters with three-winding coupled inductors are proposed to achieve high voltage conversion ratio and low input current ripple [20][21][22]. However, they are a little complex and difficult to design, which results in the circuit complexity and cost problems.…”

“…Active and passive voltage clamping is also employed in few converters to suppress the voltage stress on the power switches. 49 Some CI-based topologies like winding cross-coupled inductors, dual CI, 50 switched CI, multiwinding, 51 and multi-CI-based converters [52][53][54] are not very popular due to manufacturing complexity and larger switch voltage stress.…”
