Technicians usually match the circuit of ultrasonic cleaning machines based on their own experiences. For example, when someone is changing the water level of a cleaning tank and checking the change in current, assuming that the current change is within a certain scale, the pipe does not heat up, and the cavitation sound is strong, it is considered that the matching has been adjusted. Some people also make the machine slightly inductive when unloaded, but transition to a purely resistive state after loading. These experiences are all applicable. On the basis of existing experience, by mastering the principle of matching, ultrasonic cleaning machines can be targeted and the method of matching circuits can be more proactive, resulting in twice the result with half the effort.

The matching circuit in the ultrasonic cleaning machine sends the electrical energy output by the generator to the channel of the transducer. But it has important effects. The same type of ultrasonic cleaning machine, matched and adjusted well, will have better cleaning effect; If the matching adjustment is poor, the opposite cleaning effect will be poor.

For the same ultrasonic cleaning machine, if the cleaning effect deteriorates after a period of operation, or if the transducer is replaced, it is necessary to adjust the matching from scratch. Different from the matching of general electronic devices, the matching of ultrasonic cleaning machines not only needs to deal with the problem of variable resistance (i.e. converting the resistance value of the load to match the optimal load value of the generator), but also needs to deal with the tuning problem, that is, using the inductance of the matching inductor to offset the capacitance of the transducer, making the transducer purely resistive.
