摘要
介绍了基于空间电压矢量脉宽调制(SVPWM)控制的船用三相逆变电源装置的设计方法。SVPWM控制利用逆变器输出电压矢量的正多边形运动轨迹去逼近正弦电压的圆形运动轨迹,构造的正多边形边数越多,逆变器输出电压就越逼近基频正弦波。实验结果表明,该电源装置解决了船舶供电网络中电压波动范围大、频率不稳的问题,提高了船舶电源的供电可靠性。该装置不仅可满足使用恒频恒压正弦交流电船舶的电气设备的要求,还可满足使用变频变压正弦交流电的调速电机的要求。此外,该装置具有体积小、效率较高、直流电压利用率较高等特点。
The paper presents the design method of three-phase inverter power supply device of ship which based on space vector pulse width modulation（SVPWM）control method.SVPWM control made the regular polygon track of the output voltage vector which inverter produce to approach the circular track of sinusoidal voltage,the output voltage is more closely to sinusoidal voltage of fundamental frequency as long as regular polygon is constructed to be more sides.The expiremental results show that the three-phase inverter power supply device is resolving the trouble of power supply network of ship,such as highly wave range of voltage and unstable frequency,it improves the reliability of power supply of ship.The device is fit for the electric devices of ship which uses constant voltage and constant fre-quency sinusoidal alternating current,and fit for the timing motors which use variable voltage variable frequency sinu-soidal alternating current.Otherwise,the devices have some strongpoints,such as small volume,high efficiency and high utilize efficiency of DC voltage.
