摘要
本文研究分析了一种单相交流送风机的空间矢量脉宽调制策略。该控制策略以两相三桥臂逆变器为硬件基础,采用不平衡电压SVPWM调制非对称送风机的主、副绕组电压相角和幅值,从而实现送风机的对称运行,优化了送风机运行效率,达到风机盘管节能性提高的目的。
A control strategy of space vector pulse width modulation for single phase supply fan is analyzed. The control strategy based on two phase three leg inverter for basic hardware,using unbalanced voltage Space Vector Pulse Width Modulation（SVPWM） modulate asymmetric supply fan main and auxiliary winding of voltage magnitude and voltage phase angle,realize the asymmetric supply fan symmetric operation,operating efficiency of supply fan is optimized,achieve the purpose of improving the energy-saving of fan.
