By the means of theory, simulation and experiment, the second part of this paper is then analyzed which is on the equivalent output resistance and inductance of the selected inverter and the effect to the output voltage"s amplitude and phase caused by the different values of the inverter"s component. It is concluded that by selecting certain precision level components, the difference of the output voltage amplitude is much greater than that of the output voltage phase.

But in achieving the current-voltage conversion, with the current-voltage feedback circuit we may reach the goal in the feedback resistance using, namely premise the photoelectric current certainly, the feedback resistance is bigger, the voltage is greater.

但是在实现电流-电压转换的时候，用的电流-电压反馈电路，我们可以在反馈电阻的使用上达到目的，即在光电二极管的光电流一定的前提下，反馈电阻越大，电压越大。

A digital AGC circuit using a digital potentiometer to rep lace the feedback resistance of the amp lifierwas designed. In order to get an app rop riate gain, MCU adjusted the resistance of the digital potentiometer automatically according to the voltage value of amp lifierps output.

为使输入信号不受这一限制，设计了一种数字式自动增益放大电路，该电路采用数字电位器取代放大器的反馈电阻，单片机根据放大器输出电压自动调整数字电位器的阻值来调节放大器增益，使输出电压始终维持在所设定的上下限电压之间。

Again, this theory can only be used when the transformer is receiving a sinewave voltage as this turns-per-volt value does not reflect in any of the voltages you will get on the other windings as the "fly-back" voltage will over-ride your calculations.

每伏= 5 / 3 =同样，这一理论只能用于接收时，变压器每伏的正弦波电压，因为这原来，值不反映任何电压，你会得到你的计算上乘坐的其他绕组为"飞回来"电压过。

Switching Power Supply with the traditional distinction between :(1) not only the output voltage feedback, feedback from the average input current;(2) Current benchmarks signal voltage error signal and full-wave rectifier voltage signal sampling the product.

与传统开关电源的区别是：不仅反馈输出电压，还反馈输入平均电流；(2)电流环基准信号为电压环误差信号与全波整流电压取样信号之乘积。

The "tile"is a power unit but , is voltage and voltaic product, voltage is to maintain fundamental note type computer operation operating voltage , electric current is the situation looking at operation , power consumption having diversity but, power consumption is higher if opening DVD and the trumpet , pure await the opportune moment power consumption is lower , the entirety comes say therefore the machine power consumption is not fixed, but is status have height to have consuming an electricity low.

而"瓦"为功率单位，为电压与电流的乘积，电压为维持笔记型电脑操作的基本工作电压，电流则视操作的状况，而有不同的耗电量，如开启DVD及喇叭耗电量较高，纯待机耗电量较低，所以整体来说，机器的耗电量不是固定的，而是有高有低的耗电状况。
