| Abstract |
Toward the aim of advanced integration in power electronic, the properties of Multicell interleaved con-verters are of prime interest. Among these properties, the EMC behavior is interesting and the dynamicperformances are excellent. However their implementation requires the monitoring and balancing ofintercell currents. On one hand, the converter control must ensure a satisfying balanced distribution ofcurrents among switching cells outputs, so that magnetic components are used optimally. On the otherhand, this control must also ensure the regulation loop of the output current. To achieve these goals, wedecided to work on a direct matrix model, which allows to highlight the fast eigenmode related to thepower (common mode) and the slow magnetizing eigenmodes (differential modes). The synthesis of thecontrol and the calculus of corrector parameters are performed using inversion of this direct model. Adigital control based on this method has been implemented, and the measurement results that we present confirm it’s efficiency on current balancing. |
