Based on the power-supply demand before erecting the X-ray set,this paper discusses on the basic requirements of the X-ray set for the power-supply,and connecting with the power-demand features of the X-ray set,analyzes on the basic calculation methods for the source capacity,source resistance,source voltage,and source frequency,etc.

In data output circuit, the MOS transistor works at a high speed when the supply voltage increases in low temperature.

The causes for aberration rate are analyzed by testing the wave form aberration rate of supply voltage.

A scheme of stepless adjustable supply voltage is presented in this paper.

Studies a new energy storage piezoelectric power supply that can be used in a mechanical electronic fuze, and its mathematical model is established in the energy storing process.

Based on the tests, the energy storage characteristics of multiplayer piezoelectric power supply were studied The experimental results show that the charged voltage of capacitance C is directly proportional with the layer numbers and is inversely proportional with the volume of C.

But under the high accruacy of power will the accuracy of measurement increase if power voltage is increased properly?Will if be that the lower the inner resistance is the more accurate the measurement will be? In this paper some investigations concerning the specific problems in the experiment are conducted.

It is discovered,on the basis of an experiment on 8Hz quartz clocks,that by picking up current signal of 8Hz quartz clock,the power consumption,daily rate and power voltage can be obtained simultaneously.

As the peak current of the improved single output will be dropped by one third,it will along with an optimum pattern of routing,effectively prevent power voltage from decreasing so as to achieve a normal and stable efficiency of performance for the chips.
