Abstract

A power amplifier power consumption self-adaption device comprises a traditional power amplifier and a self-adaption module, the self-adaption module is located in a line where a DC power source supplies power to a power amplifier unit, and the self-adaption module comprises a signal arrangement unit and a controllable switching power source. The signal arrangement unit is used for performing signal phase and signal intensity arrangement on the working signal from the traditional power amplifier, generating a control signal suitable for controlling the controllable switching power supply, and sending the control signal to the controllable switching power supply; the controllable switching power supply outputs a controlled change voltage to the power amplifier unit for power supply under the action of the control signal, the output voltage intensity of the controllable switching power supply is related to the working signal, and the power supply voltage output to the power amplifier unit is automatically adjusted along with the intensity of the working signal.

Description

technical field [0001] The invention relates to the technical field of power amplifiers, in particular to a power amplifier power consumption adaptive device and method thereof. Background technique [0002] In the medical field, traditional linear power amplifiers (not involving digital Class D power amplifiers) are widely used in active medical devices because of their mature and reliable technology and no high-frequency power radiation source. In the current prior art, conventional linear power amplifiers are generally powered by a constant DC power supply. The output signal strength range of the power amplifier is very wide, and the output strength is adjusted at any time according to the needs during work. In order to ensure the power supply requirements at the maximum strength, the power supply voltage is designed to supply power at the highest voltage, but in actual work, the equipment rarely uses the maximum Intensity output, so the power supply voltage is much high...
