Abstract

The invention discloses a novel broadband high-voltage cascaded linear amplifier device. N linear amplifier modules are cascaded, and an independent direct-current power supply module is arranged in each linear amplifier module to supply power to the linear amplifier module, so that an input voltage signal can be amplified by N times, and high voltage can be output. Meanwhile, the linear optical coupling circuit is adopted to carry out signal transmission on the linear amplifier circuit, alternating current signals can be isolated, the insulation and anti-interference effects are achieved, cross-over distortion is greatly reduced, the waveform distortion rate is reduced, and meanwhile good linearity can be achieved through the linear amplifier circuit.

Description

technical field [0001] The present application relates to the technical field of linear amplifier devices, in particular to a novel broadband high-voltage cascaded linear amplifier device. Background technique [0002] The high-voltage amplifier is a signal amplifier with high-voltage amplitude output. Its bandwidth response is generally 0.1mHz-20kHz, the distortion rate is less than 1%, and the rise rate can reach 1000V / μs. Moreover, high-voltage amplifiers are divided into unipolar and bipolar amplifiers. Among them, unipolar amplifiers can only amplify unipolar DC or unipolar pulse signals, and bipolar amplifiers can amplify any AC or DC signals. [0003] High-voltage linear amplifiers are currently mainly used in industry and research fields, mainly in dielectric spectrum detection, pressure material production, electro-optic regulation, etc. In the process of high-voltage frequency-domain dielectric spectrum measurement, the complex on-site environment will affect the ...
