- 11 March 1990
A steady-state analysis is presented with complete characterization of the converter operation. A small-signal model of the converter is established. The design procedures based on the analysis are… Expand
High-efficiency, high step-up DC-DC converters
Many applications call for high step-up DC-DC converters that do not require isolation. Some DC-DC converters can provide high step-up voltage gain, but with the penalty of either an extreme duty… Expand
Three-dimensional space vector modulation for four-leg voltage-source converters

- Engineering
- Proceedings of IEEE Applied Power Electronics…
- 5 March 1995
In many single-phase power factor correction (PFC) applications, the power level can reach several kilowatts; and in some situations, the input voltage can be quite high too. For high power and/or… Expand
Optimal design methodology for LLC resonant converter
- B. Lu, W. Liu, Y. Liang, F. Lee, J. D. van Wyk
- Engineering
- Twenty-First Annual IEEE Applied Power…
- 19 March 2006
Although LLC resonant converter can achieve wide operation range with high efficiency, lack of design methodology makes it difficult to be implemented. In this paper, based on the theoretical… Expand
