Visualizing the electromagnetic field transformation inside a microwave mode conversion region has been considered to be only realizable by simulation studies. For the first time, we present a comprehensive experimental observation of the electric field transformation occurring inside a metallic waveguide TE(01)-to-TE(02) mode converter. An efficient electro-optic (EO) probe and its associated ...

The growing popularity of solid state thermoelectric devices in cooling applications has sparked an increasing diversity of thermoelectric coolers (TECs) on the market, commonly known as “Peltier modules”. They can also be used as generators, converting a temperature difference into electric power, and opportunities are plentiful to make use of these devices as thermoelectric generators (TEGs) ...

Automobile emissions such as carbon dioxide, nitrogen oxide and particulate matter are coming under progressively strict regulations worldwide. Meeting the increasingly severe requirements will require wider use of electric vehicles, including hybrid electric cars, and of high-efficiency electrified powertrains for better fuel economy. For this, implementation of still more compact, higher outp...

This paper introduces a multilevel STATCOM for electric arc furnace power quality enhancement. An eleven level cascaded multilevel converter is used to alleviate the impacts of an unbalanced arc furnace load. The STATCOM provides a power electronic-based means of embedded control for reactive power support.

This paper investigates the effect of the variation of duty ratio on the different performance parameters of the three non-isolated dc-dc converters namely buck, boost and buck-boost converter. Five important parameters dependent on the duty ratio have been identified namely output voltage, output current, effective impedance at the input, minimum inductance and minimum capacitance for continuo...

The electric vehicle (Ve) is struck by their low autonomy. To remedy this problem, we opted for the choice of a converter structure in electromagnetic switch, since it has no power dissipation in switching and conduction. The development of a control law of motorization continues saving energy and its implementation under the environment of MATLAB / SIMULINK, led to the scientific results of hi...

This paper presents the design of an auxiliary power distribution network for an electric vehicle. Efficiency is a key element in the design for any electric vehicle and a 48Vdc distribution network will be used throughout the vehicle. The high efficiency Cuk converter has been selected as the most appropriate topology to supply the various distributed loads. To achieve the best compromise betw...

In recent years the aerospace industry has made a growing effort to develop a quieter and more environmentally friendly aircraft. In particular, several research activities have been focused on innovative solutions aimed at the design/optimization of an on-board electric system fully compatible with this new approach. A first important step in the evolution towards an All Electric Aircraft (AEA...

This paper introduces a new bidirectional, isolated dc–dc converter. A typical application for this converter can be found in the auxiliary power supply of hybrid electric vehicles. A dual half-bridge topology has been developed to implement the required power rating using the minimum number of devices. Unified zero-voltage switching was achieved in either direction of power flow with neither a...

The series–parallel resonant converter (also called line level control (LLC) resonant converter) is one of the most suitable topologies for dc–dc power supply. This study introduces the LLC resonant converter into the on-board battery chargers for the plug-in hybrid electric vehicle (PHEV) applications. Different from the previous literature which has focused on the wide operation range and hol...
