Constant-frequency, clamped-mode resonant convertersTsai, Fu-Sheng January 1989 (has links)
Two novel clamped-mode resonant converters are analyzed. These clamped-mode converters operate at a constant frequency while retaining many desired features of conventional resonant converters such as fast responses, zero-voltage turn-on or zero-current turn-off, and low EMI levels, etc. The converters are able to regulate the output from no load to full load and are particularly suitable for off-line, high-power applications.
To provide insights to the operations and derive design guidelines for the clamped-mode resonant converters, a complete dc characterization of both the clamped-mode series-resonant converter and the clamped-mode parallel-resonant converter, operating above and below resonant frequency, is performed. State-plane analysis techniques are employed. By portraying the converters' operation on a state-plane diagram, various circuit operating modes are identified. The boundaries between different operating modes are determined. The regions for natural and force commutation of the active switches are defined. Important dc characteristics, such as control-to-output transfer ratio, rms inductor current, peak capacitor voltage, rms switch currents, average diode currents, switch turn-on currents, and switch turn-off currents are derived to facilitate the converter designs.
To illustrate the converter designs in different operating regions, several design examples are given. Finally, three prototype circuits are built to verify the analytical results. / Ph. D.

High voltage DC-DC converter using a series stacked topologyVan Rhyn, P. D. 03 1900 (has links)
Thesis (MScEng (Electrical and Electronic Engineering))-- University of Stellenbosch, 2006. / This thesis presents the design and implementation of a high voltage DC-DC converter using a
series stacked topology. The converter’s specifications were set by Spoornet and the converter
forms part of a DC-AC inverter to be installed in Spoornet substations. Different converter
topologies will be considered. A high frequency, high power coaxially wound transformer will be
analysed, designed and manufactured for this specific converter application. A thermal analysis of
the transformer will be carried out. The merits of different control schemes, leading to the choice of
an average current mode controller, will be discussed. This controller will be designed and
implemented to control the converter. The converter is then simulated to test and verify the
controller functionality. A two-level series stacked converter is built and tested to verify the
converter design and to test the functionality of the coaxially wound transformer. Finally, the results
obtained will be discussed.
