Abstract
An electrical energy accumulator charger having a charging circuit for each cell or group of accumulator cells. Each charging circuit contains a flyback converter (CV1) which is supplied by a power source (5 to 12) providing continuous voltage having a sinusoidal form. Each converter has a transformer (T1) whose primary winding is mounted in series on the power source between two controllable semiconductors (14 and Th1). The blocking or unblocking of the converter (CV1) oscillations is controlled as a voltage of the cell or group of accumulator cells (1). Such an arrangement compensates for the disparities in maximum charge which the accumulator cells have when manufactured.
