The ship service converter module regulates the in-zone bus voltage. The topology of the converter module is shown in Figure 1.  Voltage regulation is achieved through a combination of the feedback and feed forward control paths that are shown in Figure 2. In addition, a droop setting is used to regulate the sharing between converter modules within each zone. Also implemented is a stabilizing filter that acts to counteract the destabilizing influence of constant power loads [1]. The output of the regulator is a commanded inductor current that is used for hysteresis-based switch-level control.
