变换电压 meaning in English
voltage of transformation
Examples
- By the development of high frequency switch , low frequency transformer has been withdrawn from many domains .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。
