Abstract :
Most of the available DC - DC converter solutions are buck converters. There are very few boost converters with the performance expected of their buck counterparts. The SAC (Sine Amplitude Converter) [1] - [3] provides an elegant method of resolving the challenges of designing DC - DC converters to provide isolated, regulated and step-up voltage transformation. A real world implementation of a 50 V to 200 V step-up DC - DC converter is described. Significant data are presented to characterize the efficiency and power density of this solution compared to conventional approaches. This technique provides a +6% increase in efficiency, more than 4 times increase in power density and high gain factors.
