ABSTRACT:
A kind of 2-phase interleaving coupled magnetic
integrated VRM is studied and the corresponding passivity-based control
strategy is put forward. The model of this kind of magnetic integrated VRM is
constructed, and the performance of this 2-phase interleaving magnetic
integrated VRM of passivity-based control is verified by simulation
experiments. The results proved that this kind of passivity-based control
strategy can decrease the steady state current ripple and the dynamic output
voltage under load disturbance.
