本文所研究的变压器是那些传输相当大功率的变压器,这些变压器的设计,主要是受到铁芯和绕组的饱和或发热所限制。虽然,叙述主要是关于使用铁淦氧芯的情况(其应用十分广泛),电流变压器和高能电感器,没有特别讨论,但大部分叙述跟 这些变压器也有关。 功率变压器可应用于单频率传输,例如功率分配网路中,或者窄频带传输,例如超声波发声器,或者宽频带传输,例如天线匹配系统中。 The transformers studied in this paper are those transformers that transmit relatively high power. The design of these transformers is mainly limited by the saturation or heat generation of the core and windings. Although the description is mainly about the use of ferrite core (which is widely used), current transformers and high-energy inductors, there is no special discussion, but most of the narrative with these transformers are also related. Power transformers can be used in single-frequency transmission, such as in power distribution networks, or in narrowband transmission, such as ultrasonic sounders, or in wideband transmission, such as in antenna matching systems.
