This paper reviews different types of capacitors and auxiliary source circuit topologies and
presents an introduction to control strategies used for circuit applications reducing DC-BUS …

In this paper, an improved two-branch equivalent circuit model with a controlled current
source is proposed to describe the real-time charge/discharge and self-discharge operating …

This paper proposes a family of soft-switching bidirectional converters. In many applications,
the bidirectional converters operate over a wide range of duty cycle and load variations. In …

During the lifespan of a polymer electrolyte membrane fuel cell (PEMFC) system, some
heterogeneities between the cells constituting the stack can appear. The voltage of one …

A novel method for controlling direct voltage regulated active dc-link capacitance reduction
circuits (ACRC) is proposed in this paper. Instead of forcing the dc-link voltage of the power …

To deal with the intermittency of renewable energy resources, hydrogen as an energy carrier
is a good solution. The Polymer Electrolyte Membrane Fuel Cell (PEMFC) as a device that …

To balance dc voltage, a two-module structure based on a dc–dc three-level boost converter
is utilized. In this article, the possible operating modes for a two-module converter in the …
