  • Adaptive control for a power generator
    Patent number: 11531312
    Abstract: A power supply control system includes a power generator for providing a signal to a load. The power generator includes a power controller controlling a power amplifier. The power generator includes an adaptive controller for varying the output signal controlling the power amplifier. The adaptive controller compares an error between a measured output and a predicted output to determine adaptive values applied to the power controller. The power generator also includes a sensor that generates an output signal that is digitized and processed. The sensor signal is mixed with a constant K. The constant K is varied to vary the processing of the sensor output signal. The value K may be commutated based on the phase, frequency, or both phase and frequency, and the bandwidth of K is determined by coupled power in the sensor output signal.

  • Adaptive counter measure control thwarting IMD jamming impairments for RF plasma systems
    Patent number: 10304669
    Abstract: An RF generator in a dual frequency RF generation system. The RF generator detects IMD components resulting from interaction of the two frequencies. The IMD is reduced by adjusting the phase of the RF signal output by the RF generator. In various configurations, the IMD may also be reduced by applying a power adjustment value.
