Operation principle
Two basic units compose the circuit of the device, namely: a master frequency generator (MFG) and a powerful high-frequency inverter.
The MFG controls the inverter through ac voltage, rectangular in shape. The inverter converts the dc voltage of the power supply into the ac voltage at the ultrasonic frequency. Latching inverter transistors generate ac voltage close to rectangular at the primary winding of the output transformer. If an ultrasonic transducer be connected to the secondary coil of the output transformer, the shape of the generator voltage output appears to be close to sinusoidal. Since the inverter transistors are latching, the output voltage swing and, hence, the generator power output both depend on the inverter consumption voltage only. Therefore a controllable rectifier, built on the basis of the network voltage converter with transformless input, was used to change the power output.
