Conventional ultrasonic instrumentation has been designed to provide good performance with conventional piezoelectric transducers that enjoy a high-degree of efficiency when properly coupled to the material.
However, there are techniques and applications where very high voltages and/or long bursts of energy are necessary to produce the desired outcome, including:
Innerspec has patented a unique pulser topology that permits outputs in excess of 20kW of power in frequencies ranging from 50kHz to 20MHz. The advantages of these pulsers include:
Innerspec uses 8kW and 20kW pulsers in their high-power TEMATE instrumentation as shown in the table below:
The power output at different frequencies for the 8kW and 20kW pulsers are shown on the tables below:
Typical output currents and voltages 8Kw RF pulser at 1.5Mhz.
Typical output currents and voltages 20Kw RF pulser at 1.5Mhz.
