Power converters offer a high capability to efficiently manage electrical energy flows. Until few years ago, their primary use was in supplying motors in industrial applications and in electric traction systems. Nowadays, in addition to those fields they are employed in a very wide range of low, medium and high power applications including residential applications, renewable energy systems, dis...

The converter will be used to charge a large battery bank as well as supplying power to a constant power absorbing load. It will have to operate in either constant current mode or constant voltage mode, depending on the state of charge of the battery bank. Peak current mode control is implemented to give this functionality to the converter. The series stack topology also allows interleaved swit...

The power and energy requirements of the Joint European Torus (JET) are described. The problems involved in supplying such a load from the H. V. lines adjacent to the proposed JET sites are discussed and a cost comparison is made between the two possible components of the power supply, i. e. flywheel. generator-convertors and transformer-controlled-convertors. The proposed JET power supply syst...

This paper presents the design optimization and characterization of a microscale, permanent-magnet (PM) generator, capable of supplying 8 W of dc power to a resistive load at a rotational speed of 305 000 rpm. The generator is a three-phase, axial-flux, PM machine, consisting of a stator with Cu surface windings and a multi-pole SmCo PM rotor. Optimization of the machine geometries has enabled ...

The next generation of US Navy ships will employ high energy pulsed power weapons and sensor systems. The electrical power systems on current Navy surface ships are not capable of directly supplying instantaneous generation demand of the magnitude that these high energy loads require. As a result, there is a need for an open architecture concept for systems integration including an energy stora...

In this paper, a supervisory controller is proposed to manage the power flow in a hybrid AC/DC micro-grid for both grid-connected and disconnected modes. When the hybrid AC/DC micro-grid is connected to the utility grid, power surplus or shortage leads to power trade between the micro-grid and the utility grid. In the grid-disconnected mode, the renewable power sources (wind and solar generatio...
