Abstract
A device for balancing load of a storage device including plural elements connected in series. The device includes: a DC/AC converter including an inverter and a series resonant circuit connected to the output of the inverter; plural AC/DC converters, each including an input and an output that is connected to one of the respective storage elements and selectively supplies power to the output thereof; a transformer, the main winding of which is connected to the series resonant circuit and the secondary winding of which has outputs connected to an input of a respective AC/DC converter; and a control circuit configured to control the DC/AC converter at the current source when a number of outputs supplied with power is no higher than a threshold and moreover configured to control the DC/AC converter at a constant power when the number of outputs supplied with power is greater than the threshold.
