Problems solved by technology

However, such controllers may represent another point of vulnerability or single point of failure (SPOF) in the system, and as such, attention has recently turned to methods of providing distributed control that tend to reduce or minimize such single point of failure vulnerability

Embodiment Construction

[0029] figure 1A multiphase SMPC 100 is shown in . The SMPC 100 includes a plurality—in this case four—SMPC modules 110 . The modules are arranged in parallel - that is, they are powered by the same voltage source Vin and the current outputs I1, I2, I3 and I4 are connected in parallel to provide an output of the multiphase SMPC Iout which is smoothed by means of an output capacitor Cout . Such a parallel arrangement of known SMPC modules results in a low level of ripple such that the size of the output capacitor Cout is significantly smaller than that required for a single phase SMPC.

[0030] Each SMPC module includes interleaver 120 , control module 125 , switch driver circuit 130 and converter circuitry 140 . The interleaver and control module 125 together form a controller 160 . The converter circuitry 140 of each SMPC module can employ one of several different architectures that will be familiar to the skilled artisan. For example, figure 1 The converter circuitry s...

Abstract

A controller for a switched mode power converter (SMPC) module for use in a multiphase SCMP is disclosed, comprising: a signal generator, configured to generate a periodic signal and a clock, both having a frequency and a signal phase, and for controlling the switched mode power converter module; a first-clock and second-clock inputs configured to receive respective first-clock and second-clock signal having the frequency and respective first and second phases from neighbouring controllers; and wherein the signal generator comprises a phase adjustment circuit configured to adjust the phase of the periodic signal so as to be equidistant from the first and second phase, wherein the phase adjustment circuit determines an error signal in dependence on an offset between the phase and a mid-point between the first phase and the second phase, and a feedback circuit configured to adjust the phase in dependence on the error signal.

Description

technical field [0001] The present invention relates to distributed interleaved control of multi-phase switched mode power converters (SMPCs). The invention more particularly relates to multiphase SMPCs, SMPC modules and controllers for said multiphase SMPCs and said SMPC modules. The invention additionally relates to methods of controlling such SMPC modules and multi-phase SMPCs. Background technique [0002] Multiphase switched-mode power converters (SMPCs) are becoming increasingly important for a range of applications. The multi-phase switched-mode power converter is particularly suitable for systems that need to be robust against component failures: since power is provided by multiple subunits, a fault or failure in one subunit can be recovered by properly regulating the remaining subunits. unit is compensated. Typically, control of such multiphase SMPCs is provided by a central controller. However, such controllers may represent another point of vulnerability or si...
