Multiport Hybrid Converter for Electrified Transportation Systems

Compact and efficient power converter solutions are seen to be the backbone of future transportation systems in order cope with ongoing transition towards greener systems. Such usually comprise a main load section, which one or more propulsion traction motors connected, addition an auxiliary load, might hotels air conditioning for example. This can as low 5-10% power. Therefore, it challenging drive this from typical high system that employs medium voltage (MV) DC (MVDC) grid, is In such MVDC-integrated systems, neutral point-clamped (NPC) active NPC (ANPC) converters commonly used, where over-rated case, resulting bulky inefficient system. Thus, enable lighter system, multiport hybrid (MHC) presented paper. feed MV motor, two LV loads. Compared state-of-the-art ANPC converter, proposed MHC utilizes only extra switches per phase-leg achieve operation along increasing rating another switches. The analysed paper, its operation, modulation, mathematical derivation presented. These analyses supported by simulation experimental results utilizing reduced-scale 5 kW
