1. A process for charging a battery from an alternating current voltage which provides voltage to the battery in each direction, wherein the charging current is regulated alternatively in a boost and buck mode as a function of an error (AI) between the instant value of the current and an instant value of a supply current following a pre-determined pattern, wherein the activation of the modes of operation is controlled according to the sign of the error of the current (AI), and wherein the current is regulated in each mode by regulating the size of current impulses.
