Such a reversible-current two-quadrant converter can be realized by two back-to-back connected line frequency thyristor converters or by mean of a switch-mode converter as shown in Fig. 1-5B-2.
這種電流可逆的兩象限變流器可以用兩個背靠背的工頻晶閘管變流器或者如圖1-5B-2所示的開關(guān)型變流器來實現(xiàn)。使用這種開關(guān)型的整流器作為公用電網(wǎng)和驅(qū)動器的接口更為合適；
