But the increase of switching frequency results in higher switching loss 而傳統(tǒng)變換器開關(guān)頻率的提高必然帶來開關(guān)損耗的增加。
In order to minimize size and weight of the converters , switching frequency must be increased 為了減小變換器的體積和重量,必須提高開關(guān)頻率。
Sfvc is a simple control system that works at fixed frequency and achieves good effect under low switch frequency 采用了固定步長,在開關(guān)頻率不高時仍能取得較好的控制效果。
This results in large ripples in the torque and the stator flux linkage , and nonconstant switching frequency 這將導(dǎo)致轉(zhuǎn)矩和定子磁鏈較大的脈動以及逆變器開關(guān)頻率的不恒定。
The circuit of this scheme is simple and novel , which can be used to obtain the continuously variable switching frequencies 該方案電路簡單新穎,可利用其獲得連續(xù)變化的開關(guān)頻率。
