| Summary: | Coordinated operation among various converters within a power router (PR) is crucial for ensuring its normal operation. Since the power balance among converters in a DC PR is reflected by the DC bus voltage level, maintaining stable DC bus voltage control is particularly important as it directly affects the coordinated operation of each converter. This study proposes a coordinated control strategy for multi-port power routers based on DC bus voltage droop regulation, addressing the limitations of existing methods that rely on communication and complex control units. Based on DC bus voltage signals, all power ports automatically switch their operating states, ensuring that only one converter operates in voltage source mode at any given time, thereby maintaining the system’s bus voltage and power balance. This enables effective coordination among converters and ensures stable system operation without requiring communication between converters, simplifying control while maintaining internal system stability. |
