More Information
Summary:An R.F impedance match control system. The reflection coefficient of the system is compared to a threshold to determine a mismatch condition which is corrected by selectively changing in incremental steps the turns ratio of an autotransformer provided at the input to the load until the mismatch condition is corrected. Timing means are provided to delay each mismatch correction until initial transient conditions are stabilized and to shut off R.F. power during each turns ratio change.
