The invention relates to a method for controlling a charger (10) for electrical accumulators, comprising a step of determining cyclic ratios suitable for controlling the sinusoidal currents at the input of the charger (10), and a step of applying said cyclic ratios. Said method is characterised in that said step of applying the cyclic ratios comprises: a step of selecting a first cyclic ratio application arm and a second cylic ratio application arm from the three arms of the Vienna rectifier bridge; and, during the same electrical period of the electrical grid, the application of the cyclic ratios is carried out by one of the two application arms when the absolute value of the current is lower than a threshold value, and by both of the application arms when the absolute value of the current is higher than said threshold value.
