| description | A bidirectional power converter includes flyback converter units connected in parallel, each having a controller and adapted to accumulate power from a primary side during an ON time and to deliver the accumulated power to a secondary side during an OFF time, the primary and secondary sides being interchangeable as to the direction of power conversion, the controller operating at a boundary between discontinuous and continuous conduction modes and performing valley switching when switching from OFF to ON, one converter unit operating as a master wherein the controller is adapted to control the length of ON time in order to feedback-control an overall current output of the converter, and each other converter unit operating as a slave wherein the controller controls the length of ON time in order to feedback-control a phase delay of ON time of the slave relative to ON time of another converter unit. |
