NTS Ultrasonics

High Power Ultrasonic Drivers

NTS Ultrasonics designs and builds a very robust type of driver electronics for high power ultrasonic applications. For lower power ultrasonic applications (less than 100 Watts) we can design true sine wave output drivers. Sine wave output drivers are suitable for special applications such as particle separation.
Ultrasonic drivers, or generators, generate the electrical signals needed to make the transducers work. Mains frequency AC signals (50/60 Hz) are converted to DC, then the DC is converted back to AC at the required ultrasonic frequency. The DC/AC conversion stage design is based on a current fed push-pull inverter. This is a robust design, well suited to industrial applications where equipment must run for extended periods of time, even 24/7. This design also allows for safe transmission of the electrical driving signals over distances of 10s of metres. The driving signals are transmitted at safe levels through the cables, and only stepped up at the transducer.

NTS Ultrasonics can customize driver designs based on details supplied by the client. Customizations can include:
switched or continuous power control
a timer
external ON/OFF control
duty cycle control
various types of monitoring: temperature, current, etc
selectable drive frequency for multi-frequency transducers
computer control
