Description

technical field [0001] The invention relates to the field of electricity, in particular to a constant power output circuit and a constant power control method for an ultrasonic dental scaler. Background technique [0002] The principle of the ultrasonic scaler is to use the working tip of ultrasonic vibration to contact the surface of the tooth, and achieve the purpose of removing tartar and plaque on the surface of the tooth through physical methods. Ultrasonic tooth scalers need to use ultrasonic transducers to convert electrical energy into mechanical energy of ultrasonic vibrations. In order to obtain better cleaning results, the tooth scaler needs to output stable vibration power to improve tooth cleaning efficiency. For this reason, it is necessary to develop a scaler with constant power output, so that the scaler can output stable power and achieve better cleaning effect.
