By getting the direction function from the output AC current, the applied time of voltage vectors in one PWM period was chosen, the direction of central current was controlled for DC voltage balance.
该方法通过实时检测三相交流输出电流方向得到方向函数，利用该函数选择一个PWM周期内不同电压矢量作用时间来控制中点电流的方向，实现电压平衡。
These individuals' gait and balance function stays relatively stable over time, whereas their older counterparts deteriorate significantly.
这些个体的步态及平衡功能随时间的变化较为稳定，而与他们相对应的年龄更大的老年人则恶化更为显著。
