  • High reliability RF generator architecture
    Patent number: 9214909
    Abstract: A scalable radio frequency (RF) generator system including at least one power supply, at least one power amplifier receiving input from the power supply, and a power supply control module, and a system controller. Output from the at least one power supply can be combined and applied to each of the power amplifiers. Output form each of the at least one power amplifiers can be combined to generate a single RF signal. A compensator module controls operation of the at least one power supply. The compensator module, system control module, and power supply controller communicate in a daisy chain configuration.
    Type: Grant
