Electric pulse de-icing is a promising solution, due to its high efficiency and high power density. Challenges in pulse de-icing design include the high pulsing power rating and broad ranges of both the DC bus voltage and load voltage. A flying capacitor multi-level (FCML) converter can maintain a high power density, as the effective switching frequency at the switching node can be increased, which further reduces the filtering requirement and, hence, the size of filtering components. A buck-boost converter is able to conduct both wide step-up and step-down DC-DC conversions. Therefore, a novel topology, the FCML Buck-Boost converter topology, is proposed in this work.
