摘要
本文从电路理论中的最大功率传输定理出发,分析了超声波电发生器与普通电源的异同,提出了最大功率传输定理的扩展条件,从而将一般电源的匹配和超声波发生器的匹配这两种概念统一起来。文章应用扩展后的最大功率传输定理,从一个新的角度对超声波电发生器的最大输出功率和效率进行了分析,得到与图解法等其他方法相同的结果。
Based on the maximum power-transmitting theorem, the difference and the likeness between the ultrasound electric generator and the general electric source are analyzed. To unify the two concepts of matching, one for the general electric source and the other for the ultrasound generator, a complementary condition is put forward. The extended maximum power-transmitting theorem is used to discuss two specific circuits that are in common use in ultrasound generators.
