边电压 meaning in English

polygonal voltage

Mesh voltage of a polyphase system
多相系边电压
One is that the operation duty cycle can not be larger than 50 % because of the requirement for the transformer resetting . as a result , the voltage stress of the secondary diode is high , which limits the usage of dfc in high output voltage application
但由于变压器磁芯复位的需要，其工作占空比必须小于50 ，从而造成占空比利用率不高，变压器副边电压高，副边高频整流二极管的电压应力大。
