Automatic control amplitude of power ultrasonic instrument |
| |
Abstract: | The output power of high power ultrasonic instrument is changing along with working surroundings and it can result in the overload of ultrasonic instrument and then the damage of the instrument. This paper introdues the principle and method of controlling amplitude automatically by using multiplier technology. This technique ensures that a complete set of system can operate stably on constant power scope under different conditions. |
