Reversible direct current to direct current converter for use in car, has circuit breaker to limit variation of value of current generated by converter for predetermined length of time, when change in direction of operation is detected

摘要

The converter (1) has a detection unit for detecting a change of direction of operation of the converter between a step-down transformer operating process and a voltage increasing operating process. A circuit breaker is arranged to limit variation of value of current generated by the converter for a predetermined length of time, when a change in direction of operation of the converter is detected. A generator (5) or comparator is arranged for producing a commutation signal for controlling a set of switches (S1, S2).
