Diodes are electronic devices which rectify alternating current to direct current.
二极管是将交流电整流成直流电的电子装置。
The system generates a direct current, so using it to power DC devices locally is more efficient than switching to the alternating current needed to feed it back to the grid.
该系统产生的电流为直流电，所以用来驱动本地的直流点装置比将其转化为交流电输入电网来的更有效率。
It is common for the direct current circuit to be interfered by alternating current voltage.
直流回路受到交流电压干扰，是控制回路中容易产生的现象。
Amy Chang-chien, coordinator of this solar project, pointed out that traditional solar system has a centralized inverter to change direct current to alternating current.
万佛圣城太阳能计划协调人张简嘉乃指出，传统的太阳能系统采用中央逆变器，将直流电转换成交流电。
