“…Each electrical subsystem acts as a standalone unit, which connects to the DC-Link via either an input converter, an output converter, or both. The advantages of this configuration are discussed in more detail in [5]. Given the role of converters to adjust the power flow demands of each subsystem, these play a key role in vehicle behaviour and management of energy demands.…”

The aim of this paper is to present a new bidirectional DC-DC linearized converter model for use in power demand and recovery units mainly used in Lightweight Electric Vehicle applications. The model significantly reduces the simulation time of the experiments performed, with up to a 4450-fold decrease in simulation times with respect to the original switched DC-DC topology. The study begins with a literature review of available switched converters, after which the presented topology is selected. The object-oriented modeling language Modelica is used to implement the converter in the Dymola modeling environment. Components and base classes from the Modelica Standard Library and VehicleInterfaces library are mainly used for better interoperability. Because of the intensive use of converters in the whole vehicle and the time consumed by the converter simulations due to high frequency commutation, a linearized DC-DC converter model is proposed. Comparison tests are performed between the reference switched models and the proposed linearized models in Dymola tool to validate the linearized model behaviour. Nearly identical responses are obtained for both models, while simulation times are reduced as much as 1/4450 for the linearized converter. Furthermore, validation tests are carried out between the proposed linearized model in Dymola and a reference switched model in LTspice specific purpose simulation package for switched electronic circuits. Excellent agreement in the responses of both models is observed.

En este trabajo se analiza la operación con conmutación suave de un convertidor CC-CC bidireccional de tres puertos (CTP) para sistemas eléctricos híbridos. Se estudia el principio de control de flujo de energía y la operación con conmutación suave para establecer sus regiones de operación. A partir de este análisis se definen criterios de diseño para operar el CTP con conmutación suave en un amplio rango de funcionamiento. Los parámetros considerados son las relaciones de transformación y las inductancias de dispersión del transformador, las cuales determinan la máxima potencia que puede ser transferida. Se presentan resultados experimentales para validar el análisis.
