PhD Thesis. See publication. Selection of the Stable Range of the Equivalent Series Resistance (ESR) of the Output Capacitor for a SCALDO Regulator. This DC-DC converter is derivative of boost regulator which is modified with flyback transformer for auxiliary power of the converter itself. The new power converter is designed to reduce the.
Dr Xianwu Zeng received his MSc and PhD at the University of Manchester between 2009 and 2014. He had a broad industry experience in power converter design. He was a lead power electronics engineer in GE grid solution before, and was responsible to design valve unit for HVDC projects.
During pre-thesis and thesis-1 semester comparative study among the four types of converters has been done. Simulations of all circuits were performed. In final. The dc-dc converter inputs an unregulated dc voltage input and outputs a constant or regulated voltage. The regulators can be mainly classified into linear and switching.
First a study of di erent DC-DC converters is presented, based on that the most suit-able converter for thermoelectric application is determined. In order to maximize the harvested power, maximum power point tracking algorithms have been studied and an-alyzed. After the investigation, the single ended primary inductor converter was simulated and.
It is normal to interleaved DC-DC converters to share the input current, minimize the current ripple and increase the power density. This thesis presents an input parallel output series converter integrating coupled inductors and switched capacitor demonstrating high static gain.Learn More
In this thesis, a novel DC-DC converter known as the Coupled Inductors Combined Cuk-SEPIC' (CI-CCS) converter is explored, which is particularly attractive for these photovoltaic applications. A topological modification is investigated which provides several benefits, including increased power density, efficiency, and operational advantages for solar energy conversion.Learn More
Two soft-switching DC-DC boost topologies are investigated to extend the switching frequencies of 1200 V, 100 A SiC MOSFET modules beyond the state-of-the-art, 75 kHz. Auxiliary circuits are introduced to the switching legs of the dual-interleaved boost converter to ensure snubber assisted zero voltage zero current (SAZZ) switching of all the semiconductor devices.Learn More
