Abstract

A portable high voltage amplifier is used for amplifying small-amplitude unipolar square wave signals into unipolar high voltage square wave signals with a high slew rate, characterized in that the portable high voltage amplifier comprises a signal input end, a reverse unit, a driving unit, a transformer, an upper bridge arm unit, a lower bridge arm unit and a signal output end, wherein the signalinput end is used for inputting an external signal to be amplified, the reverse unit is used for processing the signal to be amplified to obtain two paths of unipolar square wave signals VP1 and VP2which have the same voltage amplitude, the same frequency and a phase difference of 180 degrees, the driving unit is used for processing the unipolar square wave signals VP1 and VP2 to obtain pulse signals which have a phase difference of 180 degrees and have very high source current and sink current, the transformer is provided with a primary coil, a first secondary coil and a second secondary coil, the upper bridge arm unit and the lower bridge arm unit are rapidly and alternately turned on, and the signal output end is used for outputting the unipolar high voltage square wave signals with the high slew rate.

Description

technical field [0001] The invention relates to a high-voltage amplifier, in particular to a portable high-voltage amplifier. Background technique [0002] A high-voltage amplifier is a precision electronic instrument used in an open-loop or closed-loop control system. It outputs an adjustable DC high voltage or a high-voltage signal that is superimposed on an output bias high voltage and an amplified function signal. It is widely used in quantum optics, quantum information And in the all-fiber time-domain spectroscopy system in the field of terahertz technology. [0003] Commonly used unipolar high-voltage square wave signals are mainly generated by desktop high-voltage amplifiers, such as the GD-1 high-voltage amplifier produced by the Institute of Optoelectronic Technology, Chinese Academy of Sciences, the DC high-voltage amplifier produced by Shanda Yuguang Company, and the foreign U.S.A. The burleighMODEL PZ-70 high-voltage amplifier produced by Burleigh Instrument Inc...
