Abstract
The invention relates to a high-voltage system for charging a high-voltage battery (2) of an electrically operated vehicle, optionally with alternating current or direct current, with an on-board charger (3) comprising an isolating DC / DC converter (6) with a primary circuit (11) and at least one secondary circuit (13, 14) which are galvanically isolated by a transformer, wherein for DC charging with boost function: - the primary circuit (11) can be connected to two potentials of a charging socket (15), - the secondary circuit (13, 14) can be connected in series with the primary circuit (11) via one or more switching elements (DC_Laden_400_P, S_Parallel_P, S_Parallel_N, S_Serie), - one of the potentials of the charging socket (15) can be connected to a potential of the high-voltage battery (2), and - another potential of the high-voltage battery (2) can be connected to the secondary circuit (13, 14). is.
