Power Converters for Electric Vehicles
(2012-01-18)
This thesis presents topologies and control methods to improve the efficiency and dynamic response of Electric Vehicle (EV) power converters. There are three main converters in an EV power conditioning system: a plug-in ...
Efficient Control of the Series Resonant Converter for High Frequency Operation
(2012-09-10)
Improved transient performance and converter miniaturization are the major driving factors behind high frequency operation of switching power supplies. However, high speed operation is limited by topology, control, ...
New Technologies to Improve the Transient Response of Buck Converters
(2010-02-01)
As the speed and power demands on Buck converters continue to increase, it has become time to replace the linearly-controlled conventional Buck converter. Digital circuits, such as microprocessors, are requiring higher ...
MOSFET Current Source Gate Drivers, Switching Loss Modeling and Frequency Dithering Control for MHz Switching Frequency DC-DC Converters
(2008-02-29)
The power density of a switching converter is dependent on the size of the power circuit components. Converters are operated in the hundreds of kHz to achieve high power density since the size of the converter reactive ...
Adaptive Critic-based Control of Voltage Source Converters in Microgrid Systems
(2014-11-11)
Control of microgrids, as the main building blocks of the future smart power grid, is an important problem which has initiated many research activities in recent years. The microgrid should appear to the power grid as a ...
Nonlinear Adaptive Droop Control Method for the Battery Storage Systems Operating in DC Microgrids
Conventional sources of energy like coal, gas, and oil are being depleted and renewable sources of energy are needed to meet ever-increasing energy demands. Renewable Energy Sources (RESs) like solar and wind can be ...
Asynchronous Complementary Dual Channel Current Source Gate Driver for Synchronous Buck Converters
Currently there is a push for higher switching frequency DC-DC converters, especially in mobile and computer applications. Higher frequency operation allows for better transient performance and a reduction in the size of ...
Control of a Single-Phase Grid-Connected Voltage Source Inverter with LCL Filter
(2013-10-02)
This thesis presents new control approaches for improving the performance, stability, and efficiency of a single-phase grid-connected voltage source inverter (VSI) with an LCL filter that is used in renewable energy power ...
A New DC UPS for DC Power Distribution System in Data Center
In recent years, the 380V DC and 48V DC distribution systems have been extensively studied for the latest data centers. It is widely believed that the 380V DC system is a very promising candidate because of its lower cable ...
