Pulse width modulated DC/DC converter with reduced ripple current coponent stress and zero voltage switching capability

摘要

An improved DC to DC converter is provided in particular for converters with high power density requirements. The converter comprises an input voltage source and a capacitor connected in series to the voltage source. A switching transistor configuration connects the voltage source and the capacitor alternatively to the primary windings of a transformer. The secondary windings of the transformer are connected to a full-wave rectifier and a filter. The output voltage provided at the output of the filter is modulated by a controlling means.
