Comparative Analysis of Series Connected MOSFETs with Single Switch for ZVS Turn On Converter Topology

Series-connected MOSFETs with lower voltage ratings can be an alternative for single high-voltage switches. This paper compares two switch configurations for the soft-switched power converter topology targeted for a 1400V DC grid. The first configuration is a single switch rated at 1700V whereas the other is a series connected two MOSFETs rated...

Bipolar DC grids on ships: possibilities and challenges

A Series Resonant Balancing Converter for Bipolar DC Grids on Ships

Balancing converters are an integral part of a bipolar dc grid. In this paper, we propose a balancing converter based on a series resonant converter topology. The converter operates in the capacitive region with phase shift between the upper and lower H-bridges. The converter operation is analyzed and verified with LTSpice simulation. A...

Cases of Soft Switching in a Series Resonant Balancing Converter for Bipolar DC Grids

Balancing converters are an integral part of a bipolar dc grid. Resonant converter topologies are interesting for power electronics engineers due to their soft switching capabilities. A series resonant converter topology is promising as a balancing converter in a bipolar dc grid. The series resonant converter is usually a non-inverting...

Modeling and Stability Analysis of Radial and Zonal Architectures of a Bipolar DC Ferry Ship

Electrification of ships is one of the hot topics in the marine industry. This is due to the stringent guidelines by the International Maritime Organisation (IMO) for curbing the green house gas emissions from the marine sector. In this paper, the state-space modeling approach is used to model bipolar dc grids on ships. A ferry is used as a...
