“…Switched capacitor converter (SCC) is a power circuit that implements voltage conversion by switching capacitor elements [1, 2]. It is becoming popular due to its non‐magnetic components, smaller size, and higher efficiency [3]. Owing to the employment of small area, SCC facilitates for the development of valuable products such as power‐on‐a‐chip.…”

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.

“…Many different converters are available on the market, hence switched capacitor converter is used among all kinds of converters. The main advantage of the switched capacitor (SC) converters is their smaller size, nonmagnetic components, and high efficiency [1]. In addition, by reconfiguring the topology we can generate maximum number of voltage conversion ratios (VCRs).…”

A new dual-input and dual-output switched capacitor (SC) converter is designed to operate with two independent voltage sources that provides two different output voltages. The only converter generates 32 voltage conversion ratios (VCRs). The converter is portable to operate with one or two input sources alternatively and having the ability to vary 32 voltage ratios. An efficient low power SC converter is designed for input voltage of 1.5 V to 5 V that gives dual output voltages of 1 V to 10 V. The designed converter can operate in both buck and boost modes. This SC converter has high drive capability of load current from 10 µA to 25 mA that is adjusted by operating frequency. Modeling, analysis are performed to verify the dual output converter mathematically and also verified using PSIM simulations. The mathematical results and simulation results show excellent proof of newly designed converter.

Resumo-Este artigo apresenta um Inversor ZVS PWM com grampeamento ativo de tensão que utiliza um único interruptor auxiliar. A estrutura é particularmente simples e robusta. Ela é muito atrativa para aplicações monofásicas de alta potência. As perdas por comutação e condução são reduzidas com a implementação de um circuito "snubber" simples e regenerativo que provém comutação ZVS para todos os interruptores. Suas principais vantagens são: Estratégia de comando simples, robustez, baixo peso e volume, baixo conteúdo de distorção harmônica da corrente de saída e alta eficiência. Principio de operação em regime permanente, análise matemática, procedimento de projeto e resultados experimentais de um protótipo de laboratório são apresentados.
