摘要
A circuit is disclosed for providing an 80 kilohertz sine wave to an ultrasonic transducer which includes an 80 kilohertz square wave generator driving a transistor having the primary of a transformer in its collector circuit. The secondary of the transformer drives a power transistor which has the transducer drive circuitry in its collector circuit. The transducer drive circuitry includes a transformer whose primary is connected in series with an inductor. The secondary of the transformer drives the transducer and has a capacitor connected thereacross. A third winding of the transformer is connected to have its output rectified to serve as a power supply for the square wave generator.
