基于F2812的维也纳VIENNA电源程序。本程序根据三电平六开关（Vienna）整流器的工作模态，结合两电平空间矢量（SVPWM）的工作原理，介绍了Vienna整流器SVPWM控制采用两电平SVPWM控制等效的方法。本文提出了一种适用于各种负载条件下的中点电位控制算法。
Based F2812 Vienna VIENNA power program. This procedure based on three-level six-switch (Vienna) rectifier operational modal, combined with the two-level space vector (SVPWM) works, describes the Vienna rectifier SVPWM control method uses two-level SVPWM control equivalent. This paper presents a suitable under various load conditions midpoint potential control algorithm.
