“…It is possible to generate even more number of VCRs such as

V_{o 1} = false(0.5 normal* V_{s 1} false) + false(0.5 normal* V_{s 2} false)

and

V_{o 2} = 0.5 normal* V_{s 1}

. However, such kind of implementations require two outputs to appear in one topology, which may arise cross‐regulation phenomenon at the loads [1]. Hence, Zhaikhan , et al [1] considered only decoupled VCR implementations.…”

“…The advantages of SCCs are non‐magnetic elements and it is easy for integration into ICs. Furthermore, SCC has high efficiency in open‐loop conditions for fixed input and fixed output VCRs [1, 7]. Hence, portable applications preferred SCC for high‐efficiency, low‐efficiency drop for the technological processors [8, 9].…”

Here, accurate transresistance calculations for the coupled case and mathematical modelling are provided for dual input-output switched capacitor converter (SCC). This converter offers two different output voltages and produces 36 voltage conversion ratios. The dual input-output SCC is portable and operates by considering either sources or the combination of both V s1 and V s2 as input sources. The proposed dual input-output SCC has the ability to vary 54 voltage ratios. An efficient lowpower SCC is designed for an input voltage range of 1.5-5 V and it gives dual-output voltages of 1-10 V. The proposed converter can operate in both buck and boost modes. The SCC has high drive capability of load current in the range of 10 µA to 100 mA that is adjusted by varying the operating frequency. The accurate equivalent resistance for both coupled and decoupled load cases is found and validated. The results are verified through PSIM simulations and validated experimentally. The mathematical, simulation, and experimental results give excellent proof for proposing the newly designed converter for applications requiring large conversion ratios eliminating inductors.

Utilisation of more than one energy source in the electric vehicle (EV) ensures the reliable riding of the vehicle without range anxieties. Solar PV, battery and ultra-capacitor are viable sources to power the EV. A novel dual input-dual output dc-dc converter is proposed for the integration of the above sources for the EV application. The converter can be used to transfer power between the input sources and loads/utility grid/other EVs. The proposed converter can be operated in ten different modes using the same structure by controlling the appropriate switches. The equivalent circuits with the analytical waveforms of significant modes of operation of the converter are discussed in this study. The output equations of all ten modes are derived. The theoretical analysis of the converter is verified experimentally using a 1 kW laboratory prototype and the observed experimental results are shown in the study. A strategy for selecting a mode according to the status of the vehicle, grid, battery etc. is developed. The loss breakdown analysis and efficiency profile of the converter are presented. Finally, the performance comparisons of the proposed converter with the reported converters are carried out in terms of component counts, a number of operating modes etc.
