But the increase of switching frequency results in higher switching loss 而传统变换器开关频率的提高必然带来开关损耗的增加。
In order to minimize size and weight of the converters , switching frequency must be increased 为了减小变换器的体积和重量,必须提高开关频率。
Sfvc is a simple control system that works at fixed frequency and achieves good effect under low switch frequency 采用了固定步长,在开关频率不高时仍能取得较好的控制效果。
This results in large ripples in the torque and the stator flux linkage , and nonconstant switching frequency 这将导致转矩和定子磁链较大的脉动以及逆变器开关频率的不恒定。
The circuit of this scheme is simple and novel , which can be used to obtain the continuously variable switching frequencies 该方案电路简单新颖,可利用其获得连续变化的开关频率。
