28khz 1500W Ultrasonic Generator PCB Board With Digital Display For Driving Cleaning Transducer

The 40khz ultrasonic circuit board adopts a frequency automatic tracking method to drive the ultrasonic cleaning generator and ultrasonic cleaning transducer to work in the optimal state, so as to achieve the optimal working efficiency of the entire ultrasonic cleaning machine. The power value is calculated and the output power of the ultrasonic generator is modified through a pulse width modulation circuit.

40 khz ultrasonic circuit board Due to the characteristics of ultrasonic transducer, the matching circuit in the ultrasonic cleaning machine includes two: one is power matching, the other is tuning matching. The former is to ensure that the output internal resistance of the ultrasonic power supply is consistent with the load impedance, using a transformer matching method. The latter is to make the transducer exhibit pure resistance, using a series inductance method.

The 40khz ultrasonic circuit board PWM pulse width duty cycle controls the transducer driving voltage of this link; The energy conversion driving voltage is matched and resonated through the energy conversion execution link to generate the energy conversion driving current; After calculating and processing the frequency conversion feedback loop, the transducer driving voltage and transducer driving current are converted into ultrasonic processing feedback frequency and introduced into the comparison loop.
