摘要

Ultra su00c8nico generator to provide power su00c8nica ultra - high power to a variable load, and drive circuit for an ultrasonic transducer su00c8nico. The present invention is directed to an ultrasonic generator of high power (e.g., 500 W) for use especially for providing ultrasonic energy of high power to a load variable including compressible fluids.The generator includes a generator of a triangular wave, frequ00fau00eancia variable, coupled with pulse width modulators. The output from the pulse width modulator is coupled to the pruning of an insulated gate bipolar transistor (IGBT) which amplifies the signal and provides to a coil that is used to trigger a transducer magnetoestrictivo.In a way of achieving, high voltage of 600 V DC is supplied through the collector and emitter of the IGBT after signal is provided. The output of the IGBT is a form of square wave with a voltage of + 1 - 600 v. this voltage is sent to a coil wrapped around the ultrasonic transducer.The voltage creates a magnetic field on the transducer, and the transducer magnetoestrictivas properties with which the transducer to vibrate as a result of the magnetic field.The use of the IGBT as the amplification device prevents the need for a circuit of silicon controlled rectifier (SCR) which is tipicarnente used in ultrasonic transducers, low capacity, and that would come to overheating and failure in such an application, high power car GA variable.
