Performance Analysis of Three Levels Three Switches Vienna-Type Rectifier based on Direct Power Control

The Vienna-type rectifier is broadly employed in various implementations thanks to realizable three-level operation, simple structure and controllable DC-link voltage. This paper proposes an adaptive proportional integral (PI) with anti-windup based direct power control (DPC) improve dynamic response during load change, voltage step change start up reduce current tracking errors. An PI utilized enhance of the instantaneous because regulator affected by system parameter variations. conventional used indicate availability accuracy proposed strategy. strategy performs outstanding performance copes vigorous disturbances contrast A detailed theoretical analysis approach has been performed. Extensive case studies carried out PSIM software are performed validate excellent behavior
