Abstract

The invention discloses a circuit for driving a high-power ultrasonic transducer by one square wave. At present, the power of an ultrasonic transducer in the domestic industry becomes higher and higher, so that the output power of an ultrasonic power supply is required to meet a requirement on the power of the transducer and is required to match the power of the transducer; under normal circumstances, a control circuit of an ultrasonic generating power supply is very complex in design and has relatively high requirements on the program and the performance of a singlechip. The circuit for driving the high-power ultrasonic transducer by one square wave comprises a pulse square wave voltage source VPULSE, an inverter, eight resistors, four transistors, four diodes, two transformers, two insulated gate bipolar transistors, four capacitors and a transducer. The components used by the circuit disclosed by the invention are mature, reliable, low in cost and rich in sources; a single-way square wave signal and a control signal can be input simply; a bridge current circuit is high in stability; the transformer ratio of a driving transformer is large; the rated current of the IGBT (insulated gate bipolar translator) is high; high-power ultrasonic signal output can be achieved.
