【摘要】 正弦稳态电路最大功率传输问题是电路理论课程的重要教学内容。该文以包含2个正弦激励的非正弦周期稳态电路为例,讨论多频率激励下稳态电路最大功率传输问题。非正弦周期稳态电路平均功率等于直流分量和各次谐波分量分别产生的平均功率之和,因此,非正弦周期稳态电路的负载所获得的功率至多等于电源各谐波分量单独作用时负载所获得的最大功率之和。更多还原

【Abstract】 It is an important lecture about the maximum power transfer in sinusoidal steady-state circuit.Taking two non-sinusoidal periodic steady-state circuits with sinusoidal excitation as an example,this paper has discussed the maximum power transfer problems.The conclusion is drawn that the maximum power of the non-sinusoidal periodic steady-state circuit is not greater than the sum of the corresponding maximum powers of the respective sinusoidal steady-state circuits.更多还原
