Abstract
Switched-mode power amplifiers are desired that can work across a wide range of power levels and load impedances with fast response speed while maintaining high efficiency. Such designs would be valuable for many applications including plasma generation and wireless power transfer. We introduce a new wide-range switched-mode power amplifier architecture that provides output voltage modulation, enabling it to modulate output power and compensate for resistive load variations. Dynamic frequency modulation is leveraged to address reactive load variations. The new architecture enables all the semiconductor switches to maintain zero-voltage switching across all operating conditions.
期刊介绍：
COMPEL exists for the discussion and dissemination of computational and analytical methods in electrical and electronic engineering. The main emphasis of papers should be on methods and new techniques, or the application of existing techniques in a novel way. Whilst papers with immediate application to particular engineering problems are welcome, so too are papers that form a basis for further development in the area of study. A double-blind review process ensures the content''s validity and relevance.
