In the past years, the development of topologies with step‐up capacities has been important to satisfy the new requirement of renewable source energy. This study presents a quadratic boost converter based on the reduced redundant power processing ( R ² P ² ) principle, well as the controller design methodology using current‐programmed control to satisfy the specifications of output voltage regulation. Non‐linear and linear models are developed; the latter exhibits fourth‐order characteristic dynamics with complex right‐half plane zeros. In the proposed control scheme, the current of the switch is used for feedback purposes. When the current loop is implemented, the fourth‐order dynamics are changed to a dominant first order, which simplifies the controller design of outer loop. For this loop, a conventional controller is designed. At the end, experimental results are given for a 23 W quadratic boost converter, where open‐loop and closed‐loop responses are compared.

The interconnection of basic switching converters to increase power handling capabilities in dc applications has been widely reported in technical literature. This study presents a family of switching step‐up dc–dc converters based on the principle of reduced redundant power processing ( R ² P ² ). This principle states that the power transfer from input port and output port on interconnected converters is reduced when a non‐cascading connection is used. As shown in this study, the principle R ² P ² is useful for developing new converters. These have wide conversion ratios and quadratic dependence with respect to the duty ratio. In this study, the voltage conversion ratios, average models and steady‐state operating conditions for proposed converters are derived, which are verified by experimental results.

In the technical literature the interconnection of switching converters to increase power handling capabilities on dc applications has been widely reported. This study presents a family of switching step‐down dc–dc converters based on the principle of reduced redundant power processing ( R ² P ² ). This states that the power transfer from input port to output port on interconnected converters can be reduced, if a non‐cascading connection is used. As shown in this study, the principle R ² P ² is useful for developing new converters. The resulting converters are formed by a pair of L – C networks and a pair of active switches, also they have wide conversion ratios and quadratic dependence with respect to the duty ratio. In this study, the voltage conversion ratios and steady‐state operating conditions are derived for the proposed converters, which are verified by experimental results.

This paper highlights the attempts made by the government to integrate electromobility in Mexico, despite not having a well-defined National Electric Mobility Strategy, and compares the advances, challenges and future opportunities of electromobility with other countries with similar conditions in terms of the public policy, the evolution of the electric vehicles market, the charging infrastructure, incentives and legal framework, and diffusion channels. The results showed that Mexico has made partial advances in the infrastructure, production and exportation of electric vehicles, consumer incentives and project implementation. However, the country requires strengthening strategies on the economic incentives for the user and industry, homologation of chargers, training of personnel specialised in electric vehicles, handling and destination of batteries, and defining its National Electric Mobility Strategy. As a way forward, our study suggests comparing the electromobility strategies of other countries and understanding the key aspects that might enable the successful introduction of electric vehicles.

The development of switching converters to perform with the power processing of photovoltaic (PV) applications has been a topic receiving growing interest in recent years. This work presents a nonisolated buck-boost converter with a quadratic voltage conversion gain based on the I–IIA noncascading structure. The converter has a reduced component count and it is formed by a pair of L–C networks and two active switches, which are operated synchronously to achieve a wide conversion ratio and a quadratic dependence with the duty ratio. Additionally, the analysis using different sources and loads demonstrates the differences in the behavior of the converter, as well as the pertinence of including PV devices (current sources) into the analysis of new switching converter topologies for PV applications. In this work, the voltage conversion ratio, steady-state operating conditions and semiconductor stresses of the proposed converter are discussed in the context of PV applications. The operation of the converter in a PV scenario is verified by experimental results.
