This paper compares a non-isolated DC/DC converter (interleaved Buck/Boost) and an isolated converter (Dual Active Bridge) in a bidirectional charging application for Electric Vehicles. Both converters are modeled, controlled using small-signal models, and their operation in several modes is simulated and then compared. The results of the comparison using several criteria related to automotive applications...
This paper discusses the design and control of a bidirectional battery charger for Electric Vehicles, and its operation as an active power filter when connected to the local home electrical grid. The charger is also designed and controlled in order to operate during the charging of the battery from the grid and the injection of the power back to the grid when needed. The whole system is simulated...
This paper proposes a neural network controller for a DC/DC converter used to manage the power flow of an active hybrid energy source for Electric Vehicles. The energy source is composed of a battery, an ultracapacitor and a Dual Active Bridge DC/DC converter used to optimize the power distribution between the energy sources involved. The neural network control method applied to this bidirectional...
Current-injection rectifiers have found great interest in the Power Electronics community. This is mainly due to their high efficiency related to the reduced number of hard-switching devices, and their reliability with respect to other commonly known rectifiers. This paper presents an experimental investigation of a totally passive three-phase current injection rectifier with an emphasis on the parameters...
This paper proposes a new three-phase power factor correction rectifier using current injection technique. This topology uses two active networks: an injection network composed by three bidirectional switches operating at low frequency and a current shaping network consisting of two high frequency switches and only one inductance. An input current total harmonic distortion (THD) of 8.6% and a high...
This paper deals with the analysis and design of a non-isolated 36-pulse controlled AC-DC converter for medium power rating drives, field winding supply of large alternators, magnet power supplies, etc. It consists of pulse multiplication in non-isolated 12-pulse AC-DC converter to get 36-pulse converter characteristics without employing zero-sequence blocking transformer (ZSBT). The proposed converter...
This paper investigates the state-space modeling and real-time simulation of dual-bridge matrix converters (DBMC) based on a DS1104 digital signal processor. This single board controller of dSPACE uses the matlab-simulink software as a front-end for the implementation of graphic models in block- diagram format. First, the state-space model of the converter and the SVM control system are designed with...
