This permits the SCR to control only half of the AC positive wave; half voltage is applied to the load when the SCR initially fires.

这使得SCR来控制交流正波的一半，另一半的电压施加到在SCR初始触发该负载。

Three-phase half wave controlled rectifier, hysteresis comparison mode current track control, and realization of SVPWM by S-Function are used as examples to describe the usage of the software.

并以三相半波可控整流电路、滞环比较方式的电流跟踪控制、利用S函数实现空间矢量脉宽调制为例说明了软件的使用方法。
