“…These clamping diodes in the conventional NPC converter have been replaced with active switches in the ANPC. This topology has been widely investigated for different applications, such as different transportation systems in [11], [12], and [13], wind power generation in [14], [15], and [16], and general motor drive systems in [17], [18], and [19].…”

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