Abstract

Within a More-Electric Aircraft (MEA) dc power distribution system, Half-Bridge-Active-Clamped (HBAC) converters can be used to control the power transfer between different dc buses, for example, between +/-270V to 28V dc buses. However, due to the relatively large current in the low voltage (LV) H-bridges, the switching characteristics of the converter are impacted by the related parasitic inductance, resulting in a device voltage drop. This paper illustrates the device voltage drop issue by analysing different operation modes of the HBAC converter and developing a detailed mathematical model. This model has been validated with comprehensive simulation and experimental results.
