Comparative Evaluation of Several Types of Passive Damping Branches for Grid-Connected Inverters under Passivity

The passive damping (PD) branches based on passive design can provide sufficient passivity compensation to the output admittance of the grid-connected inverter (GCI) at the cost of low damping loss. However, the type of passivity-based PD branch is only considered on the shunt RC branch in recent re...

Description
Summary:The passive damping (PD) branches based on passive design can provide sufficient passivity compensation to the output admittance of the grid-connected inverter (GCI) at the cost of low damping loss. However, the type of passivity-based PD branch is only considered on the shunt RC branch in recent reports. This paper investigates the passivity compensation capabilities of several types of PD branches. Furthermore, design guidelines for the different types of PD branches are presented based on their passive properties and damping loss. Finally, the design example is given to verify the correctness of the proposed design guidelines.
