Abstract

The invention discloses a high-voltage control power supply system for a nanomanipulator, comprising: a high-voltage control power supply for an in-situ nanomanipulator of an electron microscope, a nanomanipulator, and a host computer, wherein the high-voltage control power supply of the in-situ nanomanipulator for an electron microscope receives the host computer The motion control signal sent out is processed, amplified, and a high-voltage stable pulse voltage signal is sent out to drive the precise movement of the nanomanipulator at the nanometer scale, and at the same time, the motion trajectory of the nanomanipulator is fed back to the host computer, thereby realizing the control of the nanometer. Intelligent and precise control of the manipulator. The high-voltage control power supply of the in-situ nanomanipulator of the electron microscope includes a linear adjustable high-voltage amplifier circuit and its auxiliary circuits, and an embedded controller DSP signal controller controlled by a DSP chip as the core. The upper computer includes PC and PS handle, which can be controlled at the same time through circuit switching, and can also be controlled independently, and the conversion between the two controls can be easily realized, and the operation process is humanized and intuitive.

Description
