In this study, three different Switched-Capacitor Enhanced boost quasi Z source (SCEq-Zs) DC–DC converters are presented, out of which the converter having a switched capacitor network positioned in series with the enhanced boost q-Zs network (SCEq-Zs-3) provides the common ground path and less output capacitor stress. This converter has a high voltage conversion ratio with low voltage stress on active and passive devices like capacitors, diodes, and the power semiconductor switch in comparison to other converters. This unidirectional hybrid switched-capacitor with a quasi Z source combination provides continuous and ripple-free source current mostly suitable for fuel cell applications. This leads to reduced voltage fluctuations at the input, providing a steady source of power to the converter. The converter is comprehensively analyzed and the operating principle along with waveforms is presented in this paper. A systematic comparison with other DC–DC boost converters is brought to view. A scaled-down 200V/200W prototype for the suggested converter is developed to verify the results of the theoretical study. A maximum efficiency of 95.85 % is measured. To demonstrate the effectiveness of the suggested converter, detailed experimental findings are presented. [ABSTRACT FROM AUTHOR] |
