Ultrasonic generator, often referred to as ultrasonic power boxes, ultrasonic source occurred, ultrasonic power. It is the role of our electricity (110V, 220V or 380V, 28 or 40Hz) into a match with the high-frequency ultrasonic generator AC signal. Ultrasonic generator can be used from a linear amplifier and switching power supply circuit, high-power ultrasonic power conversion efficiency considerations from the commonly used form of switching power supply circuit. Linear power supply has its unique range of applications, it has the advantage of not demanding circuit match the operating frequency to allow continuous and rapid change. From the current industry situation ultrasound, ultrasound can be divided into self-excited and its shock power.
