IMPEDANCE-MATCHING CIRCUITS FOR MULTI-OUTPUT POWER SUPPLIES DRIVING CO2 GAS-DISCHARGE LASERS

摘要

Electrical apparatus for connecting a radio frequency power- supply having two outputs (Source A- Source B) to a load includes two radio frequency transmission - lines, each one connected to a corresponding power-supply output, transformer arrangement connects the two transmission - lines to the load (34). Each transmission - line includes a series - connected pair of twelfth- wave transmission - line sections (24A, 24B, 28A, 28B). The series - connection (26A) between the twelfth wave transmission - line sections in one transmission line i connected to the series - connection (26B) between the twelfth-wave transmission - line sections in the other by a device (38) having an adjustable impedance.
