A negative ion source test facility was developed for the ion source performance tests. In order to support the experimental research, a power feed-in system was designed, which contains a solid state radio frequency (RF) generator and a matching network of L type with high voltage transformer. The design of RF generator was presented in this paper according to the requirements and characteristics of plasma discharge of RF ion source. Combine with the impedance characteristics of plasma discharge of RF ion source, the matching network was designed with high voltage transformer, including the calculation and simulation of main parameters of each parts of matching network. The characteristic of RF power matching was studied to gets high efficiency power transferred into the RF ion source. It can generate stable plasma with high power and long pulse duration.
