| Abstract |
Energy transformations with high efficiency become more and more important in DC/AC power conversion. In this paper, the basic converter of a 1kVA pulse-width-modulated inverter is examined. First, a selection is made between several possible DC/DC converters. The classic comparison between the converter types is partially reviewed for the use of MOSFETs instead of bipolars. A comparison of the highest achievable efficiency and output power for each converter type was made. Furtheron, after a converter type was actually selected, a calculation of the different sources of power losses has been made. These calculations show how to increase the total efficiency with about 8% by minimizing the discussed losses. |
