Presented is a converter philosophy for controlled transfer and transformation of electric energy through internal series resonant circuits at high internal power frequencies in excess of 10 kHz. Control of the continuously oscillating high Q series resonant circuit is attained by adjustment of the phase angle ψr between the exciting voltage and the resonant current. Only a very small fraction of...
One would be hard pressed to describe the current status of power electronics analysis and design with a single word, but it may very well be “dynamic.” Analysts have responded to the unique challenges in Dower electronics by developing a somewhat bewildering array of analytical tools and techniques. Yet this same diversity of approach serves diverse purposes in a variety of applications.
Design and performance summaries of several aerospace TWT power processors are presented in this paper to illustrate key design concepts, key features and circuit highlights. Output voltages up to 20 kV and DC power levels up to 1 kW are discussed. The usage of the entire gamut of power processor building blocks are described, including linear and switching-mode regulation and energy-storage, self-saturating...
