| 摘 要： | 为了对电能进行高准确度的测量，需要有高稳定的电源装置，稳定交流电源可采用负反馈控制系统，但易产生自激。如在反馈系统中加入一含有延时环节的负反馈，可以解决系统闭环稳定性与开环增益之间的矛盾。

| Abstract: | In order to measure the electrical energy more accurately, we need a power source device of high stability. A negative feedback control system may be used to stabilize the alternating power supply, but it easily leads to self-excitation. If people add a negative feedback containing a delay - action link to the system, the contradiction between the system's close- cycle stability and open - cycle gain can be resolved. According to this assumption, a project about alternating steady current source of high stability is put forward. |
