A Ultrasonic transducer is a device that converts high-frequency electrical energy into mechanical energy. When a power amplifier drives a capacitive resistive load transducer at high frequency, its function is to convert the input electrical power into mechanical power, i. e. , ultrasonic power, and then transmit it. Power, impedance, frequency and other factors should be considered when driving.
Power amplifiers are used in ultrasonic testing, piezoelectric ceramics, medical ultrasound, MEMS experiments, B-H curve measurement of underwater acoustic (transducer) magnetic materials and many other fields. The main parameters of power amplifier drive transducer are selected considering output voltage, frequency, required output power, resistance and so on. AIGTEK has designed a 1 MHz Ultrasonic transducer drive circuit.
The power amplifier ultrasonic driving circuit is mainly used to cooperate with the signal source and Function generator to realize the function of driving transducer. It is used to amplify the amplitude and power of various waveform signals signal generator by the power amplifier, aIGTEK design a variety of high-voltage amplifier, power amplifier, broadband amplifier and other drive circuit systems, for example: the ATA -4000 series is an ideal high voltage power amplifier for amplifying AC and DC signals. Maximum output 310Vp-p (± 155VP) voltage, 452WP power, frequency range DC-1MHz, can drive high-voltage power load. Voltage gain, DC bias CNC fine adjustable for customers to provide a wealth of test options.
