ABSTRACT:
A bidirectional voltage converter comprises an inductive element, a primary circuit having a first chopping switch and a first diode, and at least a secondary circuit having a second chopping switch and a second diode. The first switch is switched on upon reception of a start-up signal of the primary period, and switched off when the current in the primary circuit is higher than a control signal. The second switch is switched on upon reception of a start-up signal of the secondary period, to calculate the duration of the secondary period, to count this duration, and switched off when this duration is ended.
