The ZVS-PWM commutation cell applied to the DC-AC converter
(1997-12-01)
This paper presents the analysis of a dc-ac converter using a zero-voltage-switching (ZVS) commutation cell. First, we show the cell applied to the buck converter. The stages of operation are presented along with the main ...
Electric field and electric potential due to a finite cylindrical surface charge distribution considering a linearly variable surface charge density
(IOS Press, 2016-08)
This paper proposes a fast and accurate method for determining the electric potential and the radial and axial components of electric field intensity produced by a finite cylindrical surface charge distribution. The surface ...
The electric bicycle: worldwide research trends
The bicycle has gone from being an old-fashioned recreational product to a less polluting means of transport and a compact, ultra-light personal mobility tool. This is how electrical bicycles will be used as the pillar ...
Long‐duration penetration of the interplanetary electric field to the low‐latitude ionosphere during the main phase of magnetic storms
(American Geophysical Union, 2005-11-26)
It is well known that the interplanetary electric field can penetrate to the low‐latitude ionosphere. It is generally believed that the penetration of electric fields can last only for ∼30 min because of the shielding ...

Advanced control for fuel cells connected to a DC/DC converter and an electric motor
(Elsevier, 2010-05)
The transient behavior of a polymer electrolyte membrane fuel cells (PEMFC) system under an improved adaptive predictive control with robust filter (APCWRF) is analyzed using a nonlinear dynamic, control-oriented model. ...
