Ultrasonic sweep-frequency generator, also known as sweep-frequency power supply, has been well-known in many Industrial electronic areas including measuring the response of filters, electrical components, amplifiers through a wide range of frequency bands. Since the 1990s, sweep-frequency generator circuits have been broadly used in ultrasonic cleaning industry. The design purpose of the generator is to send signals with slight changes within a certain frequency range to cleaning transducers. This method not only helps to improve the cleaning effect, but also avoids matching problems caused by single frequency ultrasonic energy and prevents damage ultrasonic component.
