1.输出功率 |
|
 |
|

若输入的正弦信号的幅度足够大，并忽略管子的饱和压降UCES，则RL上最大的输出电压幅度Ucem=VCC。在理想条件下，最大输出功率为： |

2.效率 |
|
|
|
|
|

|
|
|
|
|
|
|
|
|
|
|
|
|

|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
 |
|
|
|
|
|
|
|
|
输出功率占电源供给的比率称为效率 |
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|

|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
在理想条件下，Ucem=VCC，则最大效率为: |
