Abstract

The invention relates to a method of controlling an electrolyzing plant (10) having plural electrolyzing cells (14) providing an electrolyzing process in response to being subjected to a DC electrolyzing power, wherein the electrolyzing plant is supplied with electric power from an electric power network (12) deploying an alternating voltage, wherein a transformer (32) has a primary winding (38) connected with the electric power network, wherein the primary winding (38) has several taps (30), and a secondary winding (40) connected with an AC side (22) of an electric converter (20), and a DC side (24) of the electric converter (20) provides the DC electrolyzing power, wherein an on-Ioad-tap-changer (28) is connected with the taps, wherein a control apparatus (36) controls the on-Ioad-tap-changer. The on-Ioad-tap-changer (28) has switching apparatuses (S1, S2, S3, S4, S5, S6) for the taps, wherein each of the switching apparatuses comprise at least one solid-state switching element.
