摘要
以包含2个正弦激励的非正弦周期稳态电路为例,从理论上讨论了非正弦周期稳态电路最大功率传输问题。针对负载分别为电阻、动态网络的情况,给出了最大功率传输条件及计算结果。分析表明,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。
By taking a non-sinusoidal periodic steady-state circuit with two sinusoidal excitations as an example,the problem about the maximum power transmission of a non-sinusoidal periodic steady-state circuit is discussed in theory.In view of the resistance and dynamic network of the load,the maximum power transmission condition and the calculation result are presented.The analysis shows that the power obtained from the load of the non-sinusoidal periodic steady-state circuit is at most equal to the sum of the maximum power obtained by the load when the harmonic components of the power supply are acted separately.
