In the analog domain, the basis for the basic implementation of a two-position controller is an analogcomparator or an open-loop operational amplifier.
在模拟域,双位置控制器的主要部分是模拟比较器或开环运算放大器。

Instead of the conventional analog hysteresis comparator, the compensatory current is produced by 3-dimensional space vector modulation (3d SVPWM) technique.
不同于传统的模拟滞环比较器,采用基于三维空间矢量脉宽调制(3d SVPWM)法控制补偿电流的产生。

Inside the core there are three important models, such as digital-to-analog converter (DAC), voltage comparator and some other digital logic units.
