Here, a novel modular multilevel converter (MMC) and its associated control scheme are proposed for medium‐voltage direct‐current (MVDC) distribution systems. The voltage gain and power can achieve wide‐range expansion by expanding sub‐modules. The voltage, current, and power are shared among all sub‐modules. In addition, all semiconductor devices implement soft switching under low voltage stress and current stress by introducing an auxiliary cell in each sub‐module. By reasonably distributing the energy collected in the soft switching process, the converter realizes the self‐power supply for the drive control circuit of the high‐potential semiconductor switches, wherein the sub‐modules are turned on step by step. The structure of the converter is described and its working principle and control strategy are analyzed in detail. Finally, a 1.8 kW experimental prototype based on SiC devices is provided to achieve an efficiency of 97.3%.

“…The Dual Active Bridge (DAB) converter belongs to the isolated DC/DC type and is well-known for its advantages of high frequency operating ability, inherit zero voltage switching, and bidirectional power flow [4][5][6]. The structure of the DAB can have modified flexibly with different power sources [7][8]. The DAB converter is divided into two categories: Voltage-Fed (VFDAB) and Current-Fed (CFDAB).…”

This paper proposes a novel control design for a Current-Fed Dual Active Bridge (CFDAB) converter in boost mode. The Double PWM plus Double Phase Shifted (DPDPS) modulation is applied to the converter due to its considerable merits. A small-signal model is developed to control the output voltage stably in boost mode. Simulations of the control design for the CFDAB converter were conducted to verify the proposed model. The results show that the system can achieve high performance, not only in the dynamic response but also in the steady-state.

“…La característica común a estas topologías es que el flujo de energía es unidireccional. En aplicaciones donde se requiere un intercambio de energía bidireccional, una opción interesante es el uso de celdas constituidas por convertidores CC-CC con Puentes Duales Activos (CPDA) (Hou and Li, 2019;Liu et al, 2018).…”

Este trabajo presenta el modelado de un convertidor modular CC-CC basado en la conexión entrada serie - salida serie de dos celdas con convertidores con puentes duales activos. Esta configuración resulta interesante en aplicaciones en las cuales ambos puertos del convertidor deben soportar tensiones elevadas. A partir del análisis de las formas de onda de las principales variables eléctricas de cada una de las celdas, se obtienen las ecuaciones promediadas que permiten describir la dinámica del convertidor ante cambios significativos en las entradas de control del convertidor. El modelo promediado es linealizado entorno a un punto de funcionamiento del convertidor, obteniéndose dos sistemas de ecuaciones que permiten analizar la influencia de los parámetros constructivos de las celdas en el comportamiento estático y dinámico del convertidor. Los resultados obtenidos permiten validar en el dominio temporal los modelos obtenidos, tanto en régimen permanente como transitorio, en todo el rango de transferencia de potencia del convertidor.
