“…During the small signal analysis of different topologies, it is important to take into account that bidirectional impedance networks can be symmetrical networks, which means that values of capacitance and inductance are equal (C1=C2 and L1=L2) [9]- [11]. The voltage or current that enters the inverter can be controlled by two methods: voltage or current control, which can be direct or indirect.…”

Abstract. Silicon carbide (SiC) devices provide significant performance improvements in many aspects, including lower power dissipation, higher operating temperatures, and faster switching, compared to conventional Si devices. All these features helped increase the interest in the applications of these devices for electric drive systems. The inclusion of an impedance network to elevate DC voltage would improve performance of an electric-traction system, because the topologies of impedances networks can eliminate the need of a DC-DC converter. However, it is important to know control methods that applicable to this type of topologies to systems that are more efficient. This paper presents the analysis of a control method in a power converter topology using SiC devices with an impedance network to elevate DC voltage for electric traction applications. The proposed analisys includes the implementation of a control method in Current Fed Quasi-Z topology, with 100 kHz switching frequency, and its analysis using the simulation of the control method, the power losses in SiC devices and the stress on passive components in the impedance network. Finally, the obtained results are compared with a conventional Current Fed Quasi-Z topology built with silicon devices at a low switching frequency (2 KHz).

“…b) Esquema equivalente del convertidor Quasi Z. Para el análisis de pequeña señal de las diferentes topologías bidireccionales de las redes de impedancia, se pueden considerar redes equilibradas o simétricas, esto significa que los valores de los valores de capacitancia e inductancia sean iguales C1=C2 y L1=L2, [12]- [14] tambíen para obtener una mejor respuesta y una función de transferencia más exacta es importante considerar el valor de resistencia interna tanto de las inductancias así como la de los condensadores también denominada ESR [15].…”

“…En [53] se realiza un análisis y comparación entre tres topologías que se aplican para la implementación de sistemas de tracción, considerando el almacenamiento de energía, corriente rms y las pérdidas de potencia, una topología convencional con elevador DC-DC más un convertidor VSI (Fig. 23.a), otra que consisten en una red de impedancia Z más un VSI (Fig.…”
