临界饱和电流 meaning in English

critical saturation current

Among them , phase shifted ( ps ) full bridge ( fb ) zero - voltage - switched ( zvs ) pulse - width - modulated ( pwm ) dc / dc converter has strong competitive power in big power capacity fields . but it has some limitations such as smaller load range with zvs and larger circulation energy . the ps - fb - zvs - pwm dc / dc converter with a saturable inductor utilizes saturable inductor s critical saturable current characteristic and storage energy , to enlarge load range with zvs and improve output efficiency under light load
其中，移相控制零电压开关脉宽调制dc / dc全桥变换器在大容量领域很有竞争力，但它具有实现零电压开关负载范围小，循环能量大等限制，带饱和电感的移相控制零电压开关全桥变换器利用饱和电感的临界饱和电流特性及储能，来扩大零电压开关( zvs )的负载范围，提高轻载时的输出效率，具有非常重要的研究价值。
