基于1kV直流母线电压的1kW逆变电源设计

Design of 1 kW Inverse Power Supply Based on 1kV DC Generatrix Voltage

大型风力发电设备的智能散热风机需要电压可调的交流50Hz正弦波电源供电。介绍了正弦脉宽调制(SPWM)逆变器的详细设计过程,以风力发电设备输出的1kV直流作为逆变器输入,输出为从AC 220V到AC 110V可调的50Hz正弦波信号。

The intelligent cooling fan of large wind power generation equipments need alternating current（AC） 50 Hz sine wave power supply with adjustable voltage.This paper introduces the detailed design process of the sine pulse-width modulation（SPWM） inverter,uses 1 kV direct current from the wind power generation equipment as the inverter input,the output is 50 Hz sine wave signal with adjustable voltage from AC 220V to AC 110 V.
