This paper describes an energy management strategy for an electric vehicle (EV). The proposed EV architecture contains a pack of the batteries which presents the energy source and a pack of the supercapacitors (SC) used as power source. The pack of the batteries produces the necessary energy to move forward the vehicle while the pack of the SC produces the lacking power in acceleration and in braking...
A flexible DC micro-grid model is proposed, which is suitable for grid-connected renewable energy and energy storage. The complete circuit topology and its corresponding control strategy are given, which can make sure energy reliability, and can automatically achieve a reasonable power distribution. In addition, based on the theory of Virtual Generator (VG), a complete control strategy of each interface...
The hybridization of batteries and super-capacitors (SCs) is prevalent in the study of electrical powered vehicles. SCs, having high specific power, are able to afford large amount of energy in a short period, and thus have been used to satisfy transient load power demands and capture the braking power. In this paper, the SC, also able to afford large number of charge/discharge cycles, is used to...
This paper presents a single ended primary inductor converter (SEPIC) as a power factor correction (PFC) converter which is operated in voltage control mode for the speed control of a permanent magnet brushless DC motor (PMBLDCM) driven air-conditioner (Air-Con). The proposed converter combines the PFC and DC link voltage control in single stage and uses only one controller. The PFC controller uses...
A fuzzy controller for various types of DC motor fed by DC/DC converter is designed and presented in this paper. The fuzzy controller is designed in such a way that it can be implemented in a micro-controller or DSP processor based embedded system. The system designed has two loops with an inner ON/OFF current controller and an outer fuzzy speed controller. The later is used to change the duty cycle...
