工频变压器 meaning in Chinese
industrial frequency transformer
Examples
- Since the industrial frequency transformer fulfills the boosting voltage part , most of the inverters have such drawbacks as larger size , more weight and bigger ac noise
目前，大多数户用光伏逆变电源产品存在着体积、重量、交流噪音大等不足之处，原因在于升压环节由工频变压器实现。 - Its being used can form high efficiency insulated switching power supply without using utility power transformer . the switching power ic is selected firstly in the design of high power switching power supply , precision switching power supply , application specific switching power supply and so on in the world , which has been making switching power supply short , small , light and thin the control techniques of dc - dc switching converters are completely described and analyzed
单片开关电源管理集成电路具有高集成度、高性价比、简单外围电路、优越性能指标等优点,能构成高效率无工频变压器的隔离式开关电源,目前已成为国际上开发中、小功率开关电源、精密开关电源、专用开关电源以及开关电源模块的优选集成电路,使得开关电源正朝着短、小、轻、薄的方向发展。 - By the development of high frequency switch , low frequency transformer has been withdrawn from many domains . but in the domain of ups , linear power amplifier and the inverter output low frequency ac , for the purpose of isolation and change voltage , there is no choice but to use low frequency transformer
高频开关技术的发展，使工频变压器从许多领域中退了出来，但是在需要隔离的ups不间断电源、数码线性功率放大器、要求输出低频正弦波的dc ac变换器等许多领域中，为了隔离或变换电压的需要，以至不得不保留了低频变压器。
