This design separately uses series linear constant voltage circuit, series regulate constant current circuit and the feedback type contravariant circuit to design direct current constant voltage power supply, direct current constant current power supply and DC-DC converter.

本设计分别用串联型线性稳压电路，串联调整式稳流电路和反馈式逆变电路设计直流稳压电源，直流稳流电源和DC-DC变换器。

The principle of constant power drive is: PD converts the change of output light power of laser diode into the change of diode current, and the change of current is feed back to voltage-current converser which adjusts output current of driver to compensate the laser diode.

这样，当激光器的输出光功率衰减时，驱动器相应的增大输出电流；当激光器的输出光功率增强时，驱动器就相应减小输出电流。对许多激光器应用来说，最希望脉冲输出，因为脉冲输出只有极小的结发热。

In reference to existing price models, a new price model--price formation model is formulated, which concludes that the price of current period product can be shown as the convex combination of unit product material consumption of the previous period and current period plus the convex combination of gross profit gained when the unit product of previous period and current period is sold at current period.
