Control device for ultrasonic generator - in which switch circuit adjusts induction in resonance oscillating circuit in response to generator output sensor

摘要

Control switch circuit for an ultrasonic generator consists of a sensor (4) which measures the output signal from the generator (1) and a switch circuit (5) which can variably set the frequency of the generator by variably adjusting the oscillating frequency of the resonance oscillating circuit (2) in response to the output signal from sensor (4). USE/ADVANTAGE - Used in ultransonic machines, esp. ultrasonic welding equipment. A frequency control over a wide range is achieved as is a power or voltage control.
