Abstract
The invention relates to an on-load tap changer () for controlling voltage, comprising semiconductor switching elements (), and to a method for controlling voltage for a variable transformer (). The on-load tap changer () has a first load branch () and a second load branch () arranged parallel thereto. A partial winding () is arranged between the first and second load branches (). In the first load branch (), a first semiconductor switching element () is provided upstream of the partial winding () and a second semiconductor switching element () is provided downstream of the partial winding (). In the second load branch (), a first semiconductor switching element () is provided upstream of the partial winding () and a second semiconductor switching element () is provided downstream of the partial winding (). The on-load tap changer () consists of at least one switching module (), which comprises the first load branch () and the second load branch () of the on-load tap changer.
