Samenvatting

Low output voltage, nonisolated, DC-DC converters are the focus of much investigation. The primary application of these converters is as the voltage regulating module of low voltage microprocessors. Efficiency, power density as well as dynamic response are the primary performance criteria that are optimised. A new proposed DC-DC conversion system is presented making possible a reduction in switch RMS current ratings and both the input and output filter capacitance. This in turn leads to an increase in power density. Four bi-directional DC-DC converter topologies suitable for high power, low conversion ratios are presented, two of which employ the proposed DC-DC system and two for comparison. The direct partial voltage regulation module (DPVRM) proposed is seen to have the highest efficiency. Experimental results from the four topologies are shown and critically compared.
