Abstract

See full text

A digital programmable ultrasonic generator for driving an ultrasonic transducer includes a computer for receiving and storing a plurality of selectable programs. The programs are indicative of different modes of operation. A profile generator is coupled to the computer to receive programs and to produce a digital reference voltage indicative of a voltage profile to be generated for the mode selected. A digital frequency controller is coupled to a direct digital synthesizer for producing a predetermined frequency in response to a programmed frequency command from the computer. A process controller receives the output of the direct digital synthesizer as a voltage signal having the desired frequency and modifies the voltage depending on the mode of operation and voltage desired before driving a power amplifier coupled to the transducer to be driven.
