The Performance of battery packs is highly affected by imbalances between the series connected cells that provide the required string voltage. A modular battery implementation based on cascaded converters can have advantages over traditional centralized battery systems with add-ons active/passive balancing techniques. This paper investigates the use of a modular battery integrated within a cascaded...
To improve the efficiency of electric vehicle technology, hybrid energy sources are being incorporated. Another strategy for improvement is to facilitate energy recovery in regeneration mode. So the solution to this to use a bidirectional DC-DC converter in electric vehicles. The improvement of efficiency can be further increased by using a non-isolated bidirectional DC-DC converter. In this paper,...
In electric vehicles (EVs), Li-ion battery has been applied as the main power source. To give enough power and energy to the system, single Li-ion battery cells will be connected in series and parallel to make a battery pack. Thus, cell equalization for battery pack has been an important topic in battery management system (BMS). Recently, researches have proposed different topologies and control strategies...
This paper presents a bridgeless SEPIC topology with Power Factor Correction (PFC) to charge electric vehicle battery. The converter offers a few advantages such as reduce total component count and reduction of conduction loss during the conversion AC to DC, hence higher overall system efficiency. The PFC converter operated under continuous conduction mode (CCM) with average current mode control strategy...
A high efficiency converter topology for extracting maximum power from a photovoltaic (PV) module to charge standalone storage devices is presented in this paper. A reversed buck-boost converter enabling parallel power processing with a power switch referenced to the common return is the main core of the charging system. Small signal analysis of the proposed charging system is carried out to facilitate...
Class D amplifiers are becoming the most feasible solution for embedded audio application. However, distortions due to the non-linear nature of switching stage are the main drawback for this amplifier topology. This paper discusses the design and implementation of high fidelity audio class D using sliding mode control scheme. This design method proves to be a cost effective solution for industrial...
