“…Although it was proposed for the hybrid fuel cell system application, it can be used in other renewable energy applications such as PV generation systems. After the introduction of this converter, it has gained a lot of attention from other researchers, in terms of the analysis of the performances of the converter, the control methods, the loss evaluations, and its applications [48][49][50][51][52][53][54]. In order to reduce the ripples of the input current, an inductor has been added between the input source and the full-bridge structure in the input port as shown in Fig.…”

The application of renewable energy such as solar photovoltaic (PV), wind and fuel cells is becoming increasingly popular because of the environmental awareness and advances in technology coupled with decreasing manufacturing cost. Power electronic converters are usually used to convert the power from the renewable sources to match the load demand and grid requirement to improve the dynamic and steady-state characteristics of these green generation systems, to provide the maximum power point tracking (MPPT) control, and to integrate the energy storage system to solve the challenge of the intermittent nature of the renewable energy and the unpredictability of the load demand. In order to improve the efficiency and the power density of the overall circuit, the use of a three-port DC-DC converter, which includes a DC input port for the renewable source, a bidirectional DC input port for the energy storage system, and a DC output port for supplying the load, is a preferable solution to the traditional method using two DC-DC converters: one for the renewable sources and another for the energy storage system. In recent years, many DC-DC three-port converters have been proposed and reported in the literature. Each of these converters has its own topology and operating principle, which results in different complexities, different numbers of components, different reliability and efficiency. In this paper, a comparison of the features of different topologies of three-port DC-DC converters that have been proposed by different research groups is reviewed briefly. This review can be used as a guide for the appropriate selection of the suitable topology to meet the particular requirement of a system. The paper also discusses the potential research extension of the topologies from three-port DC-DC converters to three-port DC-AC inverters and how the voltage gain of the non-isolated three-port DC-DC converter can be improved.

“…The parameters of the HEVs are listed in Table 1. For the high voltage DC bus of the ESS, the design range of operating voltage is 250-400 V. In the case that the available energy of both the batteries and the SC is 50%, the demanded power under the following three conditions should be satisfied by the ESS [18][19][20].…”

“…On the contrary, because the fully active HESS employs two DC/DC converters and additional control circuit, this topology demands compromise in terms of cost, mass, volume, efficiency, and simplicity [15,17]. At the same time, the losses in DC/DC should not be ignored [18]. Based on the results of studies [19,20], the semiactive HESS is favored to be the most popular 2 Mathematical Problems in Engineering topology, which only employs one DC/DC converter.…”

Furthermore, under certain driving cycle and configurations, the offline CSs such as dynamic programming (DP) and Pontryagin's minimum principle algorithms could find the global optimization solution.…”

Although both battery and super-capacitor are important power sources for hybrid electric vehicles, there is no accurate configuration theory to match the above two kinds of power sources which have significantly different characteristics on energy and power storage for the goal of making good use of their individual features without size wasting. In this paper, a new performance is presented that is used for analysis and optimal design method of battery and super-capacitor for hybrid energy storage system of a parallel hybrid electrical vehicle. In order to achieve optimal design with less consumption, the power-energy function is applied to establish direct mathematical relationship between demand power and the performance. During matching process, firstly, three typical operating conditions are chosen as the basis of design; secondly, the energy and power capacity evaluation methods for the parameters of battery and super-capacitor in hybrid energy storage system are proposed; thirdly, the mass, volume, and cost of the system are optimized simultaneously by using power-energy function. As a result, there are significant advantages on mass, volume, and cost for the hybrid energy storage system with the matching method. Simulation results fit well with the results of analysis, which confirms that the optimized design can meet the demand of hybrid electric vehicle well.

“…Sin embargo, el control de velocidad de motores CD requiere de una etapa de potencia (puente H), la cual se compone de semiconductores que necesitan ser conmutados de manera adecuada porque la conmutación a altas frecuencias los daña. Por lo tanto, la estimación y el análisis de pérdidas en los semiconductores es un aspecto importante a considerar en la práctica [5], no solo por el calentamiento del semiconductor sino también por la eficiencia en términos de potencia.…”

Resumen. La vida útil de los semiconductores de potencia está en un entorno ocasionado por las pérdidas de potencia por conmutación y conducción debido a la variedad de perfiles de temperatura a los que se ven sometidos los semiconductores durante su operación. Satisfacer el desempeño de la aplicación normalmente depende de la estrategia de control. Sin embargo, cumplir el objetivo por el sistemas de control sin considerar las pérdidas que se presentan en la etapa de potencia afectara la eficiencia de la etapa de potencia y disminuirá el tiempo de vida de los semiconductores. Este trabajo analiza las pérdidas que se generan en los MOSFET´s de un puente inversor fuente de tensión trifásico, que alimenta al motor de CD sin escobillas, al controlar su velocidad empleando un controlador difuso. Para observar si hay mejora se compara la respuesta del controlador difuso con la de un controlador PID. La implementación de los dos controladores se lleva acabo con la co-simulación (LabVIEW-Multisim). Los resultados de la co-simulación demuestran que el control difuso, comparado con un PID, presenta un mejor desempeño en términos del índice del error cuadrático en el control de la velocidad, además de presentar menos pérdidas de potencia, lo cual garantiza una extensión del tiempo de vida de los semiconductores de potencia. Palabras clave: control difuso, motor de cd sin escobillas, co-simulación, pérdidas de potencia.
