Zusammenfassung: | Disclosed is a method for synchronising at least one slave control circuit, controlled by a slave control signal having pulse width modulation, with a master control circuit, controlled by a master control signal having pulse width modulation, including the following steps: the master control circuit emitting a synchronisation signal indicating a master edge of an electrical quantity; the slave control circuit receiving the synchronisation signal; measuring a delay between a slave edge of the same electrical quantity and the master edge of the electrical quantity; time-shifting the slave control signal so as to reduce the delay; and repeating the measurement step until the delay is eliminated. |
