Abstract
Official abstract text for this publication.
A high-frequency power source device includes switching element groups having a configuration in which a plurality of switching elements turned on/off cyclically are connected in parallel. One parallel connection terminal of the switching element group is connected to a positive electrode terminal of a DC power source, and one parallel connection terminal of the switching element group is connected to a negative electrode terminal of the DC power source. Respective other parallel connection terminals of the switching element groups are connected via a reactor. A pulse voltage that appears at opposite ends of the reactor due to a cyclic on/off operation of the switching element groups is applied to a load through a coaxial cable and a matching circuit.
First claim
Opening claim text (preview).
The invention claimed is: 1. A high-frequency power source device comprising: a DC power source; two switching element groups connected in parallel, one parallel connection terminal of a first of the two switching element groups being connected to a positive terminal of the DC power source, one parallel connection terminal of a second of the two switching element groups being connected to a negative terminal of the DC power source, the switching element groups being turned on a…
