A novel bidirectional dc-dc converter based on the quasi-Z-source (qZS) topology is
presented in this paper. During battery discharge, it operates as the conventional qZS full …

Current trends in technology toward the elimination of fossil fuels are increasing the value of
electric vehicles (EVs). In turn, one of the main components of EVs is an electric motor (EM) …

Rapid developments in energy storage and conversion technologies have led to the
proliferation of low-and medium-power electric vehicles. Their regular operation typically …

The paper deals with a power charger capable of quick simultaneous charging of several
unevenly discharged batteries. The charger is designed for use in conjunction with a …

In the product development process of a prototype, the most noteworthy task is to select
important engineering characteristics (ECs) to avoid early stage failures such as design …

This paper presents an analysis of the opportunity to increase the price availability of small
electric vehicles, such as electric scooters, such as bicycles and wheelchairs, by applying …

This paper deals with the problem of the defining optimal switching times in modular
multilevel converters (MMC) with independent voltage sources, if no pulse width modulation …

The paper deals with expandable motors for power assist wheelchairs. Significant part of the
users of such wheelchairs are the persons, who are highly motivated to use their …

The purpose of this paper is to introduce readers with a proposal of a new approach of
permanent magnet synchronous motor with arc shaped stator for wheelchair application …
