Abstract
Disclosed are switched-mode DC-DC power converter modules, SMPC controllers, and distributed-control multiphase SMPC systems. The controller comprises: a reference clock; a synchronisation input configured to receive a first synchronisation signal; a synchronisation output configured to transmit a second synchronisation signal; a control unit configured to control the operation of the SMPC module with a phase determined by the reference clock signal or the first synchronisation signal; a delay line configured to generate the second synchronisation signal by adding a delay to the selected one of the first synchronisation signal and the reference clock signal; a fault detection terminal; a memory configured to store a datum corresponding to a number N of SMPCs in the system; and a delay calculation module configured to calculate the delay in dependence on the datum and the signal at the fault-detection terminal. Associated methods are also disclosed.
