Abstract

The invention discloses an ultrasonic cleaning power system which is used for controlling output power of an ultrasonic transducer. The ultrasonic cleaning power system comprises a network source rectifier filter module, a voltage-controlled oscillator, a microcontroller, a PWM driving module, a power inverter and a transformer, wherein the network source rectifier filter module is connected with the power inverter, the microcontroller is connected with the power inverter through the PWM driving module, the power inverter is connected with the ultrasonic transducer through the transformer, and the voltage-controlled oscillator is connected with the microcontroller. According to the ultrasonic cleaning power system, ultrasonic frequency of the ultrasonic cleaning power system is directly output through the microcontroller, the phenomenon that an external voltage-controlled oscillator directly outputs the ultrasonic frequency to cause frequency variations in the prior art is avoided, meanwhile, power regulation of the ultrasonic transducer is directly completed internally through the microcontroller, and a regulating circuit is not needed additionally. The circuit structure is simplified, miniaturization requirements of electronic products are met, and competitiveness of the products on the market is improved.

Description

technical field [0001] The invention relates to the technical field of ultrasonic cleaning, in particular to an ultrasonic cleaning power supply system. Background technique [0002] The frequency of the existing ultrasonic cleaning power supply system mainly controls the power of the ultrasonic transducer through the frequency signal generated by the external voltage-controlled oscillator or the output frequency signal of the microprocessor analog oscillator. When working, the power adjustment generally adopts gap work, Thyristor voltage regulation, changing PWM (Pulse Width Modulation, pulse width modulation) duty cycle and other methods. [0003] However, the frequency generated by the voltage-controlled oscillator is prone to frequency drift, and the method of simply using the microprocessor to simulate the oscillator output frequency signal has the problem of difficult signal processing, such as changing the duty cycle of the PWM signal. Circuit to achieve; power adjus...
