关于“基于展开式AC-DC变换器中T型桥前沿对齐调制优化定时控制”的勘误

In [1], during the production and typesetting stage, (3) was mistakenly replaced by (4). The correct forms of (3) and (4) are provided as follows: \begin{align*} &\Delta {{v}_{ds - x3 + }} = - {{K}_c}\Delta {{v}_{ds - x3 - }} \tag{3}\\ &\Delta {{v}_{ds - x2}} = {{v}_{pn}} = \Delta {{v}_{ds - x3+}} - \Delta {{v}_{ds - x3 - }}. \tag{4} \end{align*}
