Abstract
Embodiments shown and described herein relate, in general, to systems and methods for driving ultrasonic transducers and, more particularly, to systems and methods for controlling the output of high power ultrasonic transducers and improving performance of ultrasonic systems.
Claims5
A method for controlling an ultrasonic transducer, the method comprising:
- providing a generator;
- providing an ultrasonic transducer having a first stack and a second stack, wherein the first stack is configured to be reverse phased with respect to the second stack such that the first stack is in compression when the second stack is in tension;
- transmitting a first ultrasonic signal to the first stack with the generator, the first ultrasonic signal having a first frequency;
- and
- transmitting a second ultrasonic signal to the second stack with the generator, the second ultrasonic signal having a second frequency;
- wherein:
- the first frequency is different from the second frequency,
- the generator comprises a transformer having a first winding and a second winding, the first winding being wound in a direction opposite the second winding, and
- the first winding is configured to drive the first stack and the second winding is configured to drive the second stack.
