Description

(54) Connection of an ultrasonic multi-wave power converter

The invention relates to the connection of an ultrasonic multi-wave power converter.

Hitherto known connections of ultrasonic half-wave power converters to the power generator are converted so that the two terminals of the half-wave ultrasonic transducer are connected to two terminals of the secondary winding of the output transformer, one of which is usually grounded. A disadvantage of said wiring is that the power supply of the multi-wave converter does not allow two adjacent inverters to be separately and separately electrically driven by a 180 ° phase shift resulting in oscillation as a full-wave or multi-wave converter with the power of each half-wave converter.

These disadvantages are overcome and the technical problem is solved by the connection of the ultrasonic multi-wave power converter according to the invention, which is based on the fact that in each adjacent pair the winding starts of the first and third half-wave ultrasonic transducers are connected to the start of the secondary winding of the ultrasonic generator output transformer. The winding starts of the second and fourth half-wave ultrasonic transducers are connected to the end of the secondary winding of the ultrasonic generator output transformer. The winding ends of the first and second half-wave ultrasonic transducers, together with the winding ends of the third and fourth half-wave transducers, are connected to the center of the secondary winding of the ultrasonic generator output transformer.

The advantage of incorporating an ultrasonic multi-wave power transducer is that it can obtain higher ultrasonic power for the specified loads, since it is an ultrasonic transducer of a multi-wave, for example n-wave, consisting of at least two half-wave transducers suitable for phase-wiring. The resulting frequency of the multi-pitch ultrasonic transducer corresponds to the approximate resonant frequency! individual half-wave ultrasonic transducers. Additional ultrasonic portable cells or concentrators can be coupled to the multi-wavelength ultrasonic transducer in a known manner. The resulting ultrasonic power of a multi-wave composite ultrasonic transducer consists of the sum of the partial ultrasonic powers of the half-wave ultrasonic transducers. Such a multi-wavelength ultrasonic transducer multiplies the ultrasonic power required for heavy loads.
