低頻激勵器-
In the sub block circuit design, the contents that the author had introduced include : the principle of band gap voltage reference and the design technique in low power supply ; the analysis of spike pulse noise rejection, frequency divider and dead time in oscillator and control circuit ; the selection of the width and length ratio of four switches and 2x / 1x mode change point in driver and mode selection circuits
在子電路設計中，作者比較深入分析的內容有:基準電路的原理及低電源電壓下基準電路的設計;振蕩器和控制電路中尖峰脈沖噪聲抑制、兩分頻電路及死區時間設定;驅動及模式選擇電路中開關管的寬長比的選擇及模式轉換點的設計。 -
This can be reduced by borrowing close loop feedback which cost great and make the system more complex. with charge driver the pizeo acuter works under ideal linear. but charge driver is lack of low frequency stability
而採用電壓驅動方法控制壓電陶瓷，開環時存在遲滯、蠕變和位移非線性;採用電荷驅動方法，開環控制線性良好，但低頻穩定性差。 -
The driver adopted the technique of automatic power changing between high and low voltage and the driving mode of constant current cutting wave, so that the low - frequency vibration of the stepping motor was reduced and the high - frequency torque was increased
該驅動器採用高、低壓電源自動切換供電技術和恆流斬波驅動方式，降低了步進電動機的低頻振蕩，提高了步進電動機的高頻力矩。 -
Experiments have proved that the developed subdivision driver is not only smaller, sampler in system, can shorten the delay time, improve the stability in low frequency and the torque - speed characteristic in high frequency, but has good self - adaptation and self - protection ability, and its stability and reliability are higher
實驗證明，所研製的步進電機驅動器不僅體積小，簡化了系統設計，減少了級延遲，改善了低頻穩定性和高頻矩頻特性，而且有良好的適應性和自保護能力，提高了驅動器的穩定性和可靠性。
