Embodiment Construction

[0032] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. (Recheck the following content against the letters of the claims)

[0033] like figure 2 Shown is the schematic diagram of the proportional amplifier circuit driven by piezoelectric ceramics.

[0034] In order to design a fractional-order proportional amplification circuit, an integer-order proportional amplification circuit should be obtained first. The principle of the integer-order proportional amplification circuit is:

[0035] Take PA85 as an example for the high-voltage operational amplifier U5. The positive and negative input terminals of PA85 are connected in parallel with diodes D1 and D2 to obtain a voltage difference of plus or minus 0.7V to avoid unstable operation of the operational amplifier. The reference power supply is provided by the isolated bipolar switching power supply. The power supply reference terminal of PA85 is pr...

Abstract

The invention relates to on-demand piezoelectric ink-jet 3D printing, can also be used in other related fields of piezoelectric ceramic driving, and particularly relates to a design method of a fractional order calculus proportional amplification circuit applied to a piezoelectric nozzle, and in the proportional amplification circuit, a nominal resistor is used for replacing a feedback resistor. The piezoelectric ceramic driving circuit is used for driving voltage signals of the piezoelectric ceramic, is simple in design structure, and provides a novel solution for suppressing system oscillation caused by a piezoelectric ceramic load.

Description

technical field [0001] The invention relates to the field of piezoelectric ceramic drive circuit design, in particular to a design method for a fractional-order calculus proportional amplification circuit applied to a piezoelectric nozzle. Background technique [0002] 3D printing technology is becoming more and more mature, and is widely used in product design, medical treatment and industrial production, and has achieved huge economic benefits. Inkjet 3D printing technology is an important branch of 3D printing technology. Its forming principle is mainly based on droplet ejection, that is, external force forces the forming material to be sprayed from the nozzle to the substrate in the form of fine droplets (or liquid flow) to form a two-dimensional Graphics or 3D entities. According to the state of the ejected droplets, the free-forming system of droplet jetting can be divided into two types: Continuous Printing (CP) and Drop-On-Demand (DOD). When the controller sends ou...
