| 摘 要： | 为了提高电机的功率因数，降低开关损耗，基于气隙磁通控制原理，以电磁量组合来逼近圆形磁链轨迹，而电压矢量的选择对应不同开关模式，因此构成电压矢量控制ＰＷＭ逆变器。利用Ｃ语言仿真，该法输出电压较一般ＳＰＷＭ逆变器提高１５％，每次状态切换只涉及一个元件，开关损耗降低，且模型简单，适用于各种ＰＷＭ调速装置。

| Abstract: | In order to increase the motor's power factor and decrease the loss of switch,based on the control theory of magnaflux of magnetic air gap,the circular track of magnaflux is combined with the voltage vector.As the choice of voltage vector is relevant to different switch modes,it is possible to constitute the voltage control inverter.When the computer language C is used for simulation,the output of voltage is 15% higher than that with the common SPWM inverter.The power loss can be decreased because only one apparatus is switched each time for the changing of on off status.The model is so simple that it appies to all kinds timing device of frequency conversion. |
