New modulation scheme and voltage balancing control of modular multilevel converters for modern electric ships

Abstract: The distinctive features such as fault-tolerability, modularity, power and voltage scalability have propelled modular multilevel converters (MMCs) as one of the emerging power converter topologies for marine applications. Pulse-width modulation (PWM) schemes are widely used to control the MMCs due to their good control capability and ability to operate at higher switching frequencies. However, the required number of carriers for gating signal generation drastically increases with the submodule count per arm in… Show more

“…2 is implemented using the PLECS and MATLAB software platform with the parameters given in Table 3. The DC‐bus voltage selection and parameter sizing are performed as per the methodology discussed in [6, 39]. Most of the MMC studies assumed that all capacitors of SM having an equal capacitance (3.3 mF), the SM power and VB control approaches show identical performance in terms of waveform quality, power loss, and capacitor ripple.…”

“…In this study, the performance of an MMC with the proposed balancing technique is evaluated at different operating conditions and compared with the conventional VB approach [6]. Simulation studies of a single‐phase MMC using the VB control approach are carried with the aforementioned capacitor values and their results are shown in Fig.…”
