GENERATOR FOR EXCITING ULTRASOUND RADIATORS Russian patent published in 2018 - IPC H03K3/02 

FIELD: physics.

SUBSTANCE: generator device (GD) contains a concatenated signal conditioner, a control unit and an N-channel SPIKE, the outputs of which are connected to the inputs of the N-channel transformer adder through consistently included channels of the N-channel KUM and N-channel threshold sensor current, the first and the second outputs of which are connected through a low-pass filter and a current sensor with the first and the second excitation buses of acoustic emitters, and the output of the N-channel threshold current sensor is connected with the ban entry of the N-channel SPIKE, further the first and the second threshold amplifiers, an amplitude detector, an analogue-to-digital converter, and a digital adder are introduced, wherein the signal conditioner additionally contains a code on the data bus system amplitude and output permissions, and the control device includes a parametric amplifier with amplification and subtractive code bus device, the output of which is an output of the control device.

EFFECT: increasing the reliability under condition of ensuring safe operation under conditions of a significant change in the load impedance, which ensures uninterrupted operation under extreme operating conditions.
