Implementation of sliding mode control for current sharing in fixed frequency voltage regulator modules

Voltage regulator modules (VRMs) have to maintain perfect current sharing between modules in both static and dynamic loading. In this study, sliding mode control was applied to both the voltage loop and the current share loop of the two-phase VRM with the aim of providing an effective current sharin...
