Abstract: This paper proposes a new control strategy for bidirectional DC-DC converter. This strategy aims at controlling a bidirectional DC-DC converter to behave like a virtual conductor. As a matter of fact, the voltage difference between the terminals of any conductor is zero volts. Conversely, the main target of this proposed control strategy is to keep the voltage difference between the c...

Photovoltaic converters are important converters for the application of renewable energy sources because of the direct conversion of solar energy to electric energy. They have some advantages such as low weight and feasibility of small scales, but they are more expensive compared to other types of energy converters. Therefore, it is important to absorb the maximum solar energy in order to incre...

Silicon carbide (SiC) devices provide significant performance improvements in many aspects, including lower power dissipation, higher operating temperatures, and faster switching, compared to conventional Si devices. All these features helped increase the interest in the applications of these devices for electric drive systems. The inclusion of an impedance network to elevate DC voltage would i...

Thermal to electric energy conversion with thermophotovoltaics relies on radiation emitted by a hot body, which limits the power per unit area to that of a blackbody. Microgap thermophotovoltaics take advantage of evanescent waves to obtain higher throughput, with the power per unit area limited by the internal blackbody, which is n2 higher. We propose that even higher power per unit area can b...

Electric Vehicles (EVs) require energy storage system that can address its fast changing load requirements such as sudden acceleration or quick regenerative braking by being able to supply or absorb high power as demanded. Lead Acid Batteries, commonly used in cheaper EVs (like electric tempo in Nepal), can properly supply these variable loads and get recharged but this mode of operation drasti...

Have you ever wondered what it would be like to have a self-sustained charging system that does not cost you any money on your electric bill? Electric car owners know that even though their cars do not require gasoline to run, they will require electricity and like everyone else that is tied to the grid will have to pay a price per kilowatt hour that is determined by their utility company. With...

As the aircraft industry is moving towards the all electric and More Electric Aircraft (MEA), there is increase demand for electrical power in the aircraft. The trend in the aircraft industry is to replace hydraulic and pneumatic systems with electrical systems achieving more comfort and monitoring features. Moreover, the structure of MEA distribution system improves aircraft maintainability, r...

The development of a high-power-density three-phase ac converter has been a hot topic in power electronics due to the increasing need in applications like electric vehicles, aircraft and aerospace, where light weight and/or a low volume is usually a must. There are many challenges due to the complicated relationships in a three-phase power converter system. In addition, with the emerging SiC de...

Very high values of efficiency in electric power conversion, electric energy saving requirements and power converter component optimization are priorities in design and construction of any type of modern power electronic converters. Moreover, if such power converters are connected to battery power source or other "weak" power source (as, for instance, fuel cells), additional design problems app...
