Abstract
High power converters have found their way into many industries. Variety of industries processes have increased their requirements in power level, economy of scale, efficiency, new control method, new topologies and using new technologies (like new semiconductors). The incentive to move to higher frequencies is not only given by the reduced sizes of the passive components, magnetic core losses, but also the application demands. It is thus clear that much can be gained from moving to a design that enables operation at very high frequency. Hence in the recent years, high frequency high power converters have been one of the most active areas in research. In this PhD research project high power converters have been considered, regarding to their power level, as two categories of high instantaneous and high average power converters. High frequency high instantaneous power converters mostly known as pulsed power supplies are studied as the main aspect of this research, and high frequency high average power converters are investigated with the specific intention on high power piezoelectric transducer applications as the second aspect.
