【摘要】 在正弦稳态电路的分析中,很多教材均讨论了最大功率传输问题。所讨论的问题一般都是针对已知的含独立源的线性网络,通过改变负载来讨论获得最大功率的条件。但在实际问题中,有时会遇到电源和负载不可变,而需设计匹配网络的问题。一般教材中没有给出这种情况下的最大功率传输条件的证明。本文讨论了当电源及内阻抗和负载阻抗不变时,通过设计一无损的LC网络实现最大功率传输,并给出了这种情况下负载获得最大功率条件的证明。更多还原

【Abstract】 The question of the maximize the average power transferred to a load in sinusoidal steady-state analysis is frequently discussed in many teaching materials.The maximization is often obtained by adjusting the load itself for a given power-supplying network.However,it is sometimes encountered that both the power-supplying network and the load is given by inserting the network to maximize the power transferred to the load in applications.The results of the maximum power transfer have not been given in the existing teaching materials in this condition.This paper discusses the problem of maximum power transfer by inserting a LC network between the power supply and the load.The results of maximum power transfer is derived in the above condition.更多还原
