2000W 33KHZ 40KHZ PCB Type Ultrasonic Generator Circuit Board For Ultrasonic Washerdish Machine

The drive motherboard circuit of an ultrasonic cleaning machine is a sweep frequency power supply used for ultrasonic cleaning machines, which consists of a main circuit and a control circuit. The main power circuit consists of a rectifier, filter, half bridge inverter circuit, transformer, and resonant circuit. The control circuit generates a sweeping control signal with a certain bandwidth to drive the power transistor in the main circuit. The control circuit consists of integrated circuits, power transistors, pulse transformers, operational amplifiers, voltage comparators, الخ.

The circuit design of the utility model for driving the motherboard circuit of the ultrasonic cleaning machine ensures that the average emission power of each transducer of the cleaning machine is consistent, and reduces the influence of physical parameters on the ultrasonic emission power, making the workpiece clean uniformly and simplifying operation. The inverter of this driving power supply is composed of power MOSFETs and adopts PAM technology. The power conversion circuit uses series resonance mode, and the control circuit has the function of automatically tracking and adjusting the resonance circuit current. The circuit structure is simple, the power transistor loss is small, the anti-interference ability is strong, the reliability is high, and the output power can be easily adjusted

The drive motherboard circuit of ultrasonic cleaning machines is mainly used in digital ultrasonic cleaning machines, small ultrasonic cleaning machines, industrial ultrasonic cleaning machines, stainless steel ultrasonic cleaning machines, الخ
