摘要
本文讨论了线性无独立源二端口和多端口网络的功率叠加性问题。指出,在网络自身满足一定条件,并且端口所接独立电源符合某种要求时,网络消耗的总功率满足叠加性。用网络端口参数之间的关系描述了这些条件。端口所接的独立电源区分为三种情况:全部为电压源;全部为电流源;部分为电压源,部分为电流源。举例验证了第三种情况下的功率叠加性。这些内容可以扩展人们对电路叠加性质的认识。
This paper discusses the power superposition properties of linear two-port and multi-port networks without independent sources within the networks.It is pointed out that when the network meets certain conditions and the independent sources connected to the ports meets necessary requirements,the total power consumed by the network satisfy the superposition properties.These conditions are described by the relationship between the network's port parameters.The independent sources connected to the portsare divided into three cases:all are voltage sources;all are current sources;some are voltage sources and some are current sources.An example is illustrated to verify the power superposition properties for the third case.These contents can expand people′s understanding to the superposition properties of the circuits.
