在研究电源输出功率与效率的关系时，一般只做定性分析．本文试图对电源输出功率与效率做一般性定量比较．１ 电源输出功率为最大时的条件１．１ 输出功率如图１所示，电路消耗在负载电阻Ｒ上的功率可用下式表示：图１Ｐ＝Ｉ２Ｒ＝［Ｅ／（Ｒ＋ｒ）］２Ｒ＝Ｅ２Ｒ／［（Ｒ－
In the study of the relationship between power output power and efficiency, generally only qualitative analysis. This article attempts to make a general quantitative comparison of power output power and efficiency. 1 Conditions when the power output power is maximum 1.1 Output power As shown in Figure 1, the power consumed by the circuit on the load resistor R can be expressed by the following equation: Figure 1P=I2R=[E/(R+r)]2R=E2R/ [(R-
