The operating principle of space vector pulse width modulation (SVPWM) is first described, and then the proposed self-tuning space current vector PWM (STPWM) technique is introduced.

首先介绍空间向量脉宽调变技术的基本原理，接著说明所设计的可自我调整参数之空间向量电流控制技术（STPWM）。

In a second sub-mode ('low output power sub-mode'), VOUT is regulated using pulse width modulation, but the converter switching frequency is fixed at a first frequency.

在第二子模式（“低输出功率子模式”）中，使用脉冲宽度调制来调节VOUT，但转换器开关频率固定在第一频率。
