  • Dynamic ultrasonic generator for ultrasonic spray systems
    Patent number: 9242263
    Abstract: An ultrasonic generator is provided. The ultrasonic generator includes an amplifier for outputting a drive signal to an ultrasonic atomizing nozzle, and a microcontroller, coupled to the amplifier, to control an output power of the amplifier. The microcontroller includes a load leveling operating mode in which the output power of the amplifier fluctuates to match changing load conditions of the ultrasonic atomizing nozzle.
