Ultrasonic power generator
MARP version 1.3

  

This generator was created as a part of a device for ultrasonic therapy.
It is designed in modular form and composed from following boards: control board, power generator board and radiator with screening function. All together in sandwich form.

• Working frequency: 1 and 3 MHz 
• Full digital frequency synthesis, integrated microcontroller. 
• Maximal power output: 30W; 
• Two switchable transducer outputs 
• Impedanc matching for two frequency ultrasonic heads (1 and 3MHz) 1cm2, 4 - 5cm2 and 10 - 12cm2; 
• Continuous power mode
• Burst mode with adjusable repetition rate of bursts between 10 and 150Hz; aith 10Hz Step. 
• Step wise controlled ratio between pause and power: 5%, 10%, 20%, 25%, 50%, 100%; with 5% step. 
• Power regulated between 5 and 100%; 
• Analyser of impedance for controlling the contact between transducer and skin.
• Galvanic isolated output transformer, allowing to apply additional voltage to the electrodes of transducer.
• All parameters controlled via digial lines with 3,3 V standard.
