“…The heatsink represents a non-negligible element because of its weight and size, and because MEA power converters are generally in a harsh environment [28]. Thermal performances impact the component's functioning (semiconductors, insulation, core…) and so the reliability of the converter.…”

The More Electric Aircraft (MEA) has motivated aircraft manufacturers since few decades. Indeed, their investigations lead to the increase of electric power in airplanes. The challenge is to decrease the weight of embedded systems and therefore the fuel consumption. This is possible thanks to new efficient power electronic converters made of new components. As magnetic components represent a great proportion of their weight, planar components are an interesting solution to increase the power density of some switching mode power supplies. This paper presents the benefits and drawbacks of high frequency planar transformers in DC/DC converter, different models developed for their design and different issues in MEA context related to planar's specific geometry and technology.

“…In addition, by fulfilling expression in Equation (10) and ϕ ≥ (1 − (D 2 + D 1 )/2)·π from the third condition (lower boundary for SM 3 *, Table 1, Case II), all switches for SM 3 * get soft switching, see Table 6. By fulfilling expression in Equation (10) and ϕ ≥ (1 − (D 2 + D 1 )/2)·π from the third condition (lower boundary for SM 4 , Table 1, Case II), all switches for SM 4 get soft switching. Finally, by fulfilling expression in Equation (10), ϕ ≥ (1 − (D 2 + D 1 )/2)·π from the third condition (ϕ values less than the lower boundary for SM 5 , Table 1, Case II), and ϕ < 1 from the fourth condition, all switches for SM 5 get soft switching.…”

“…The aeronautics industry is betting on improving emissions and reducing fuel consumption by replacing mechanical and pneumatic systems with electrical systems. In Reference [4] is shown a DAB working in harsh environments with high temperature as a component of an electric actuator; Reference [5] shows a DAB as an interface between the battery storage system and DC bus. Additionally, for electric ships [6,7] and smart grids [8][9][10], DAB converters can be seen as an interface component in the medium-voltage grid.…”

General Analysis of Switching Modes in a Dual Active Bridge with Triple Phase Shift Modulation

This paper provides an exhaustive analysis of the Dual-Active-Bridge with Triple-Phase-Shift (DAB-TPS) modulation and other simpler ones, identifying all the possible switching modes to operate the DAB in both power flow directions, and for any input-to-output voltage range and output power. This study shows four cases and seven switching modes for each case when the energy flows in one direction. That means that the DAB operates up to fifty-six different switching modes when the energy flows in both directions. Analytical expressions for the inductor current, the output power, and the boundaries between switching modes are provided for all cases. Additionally, the combination of control variables to achieve Zero-Voltage-Switching (ZVS) or Zero-Current-Switching (ZCS) is provided for each case and switching mode, by showing which switching modes obtain ZVS or ZCS for the whole power range and all switches-independent of the input-to-output voltage ratio. Therefore, the most interesting cases, switching mode and modulation for using the DAB are identified. Additionally, experimental validation has been carried out with a 250 W prototype. This analysis is a proper tool to design the DAB in the optimum switching mode, reducing the RMS current and achieving to increase efficiency and the power density.

“…An example if this approach is given in [26], where the goal is to eventually develop a like for like module replacement for existing 1200V 40V Silicon power modules. Extreme temperature tolerance is a particular advantage of SiC [27], leading to very good high temperature performance.…”

“…With the very small commutation time present in wide band gap devices, methods to accurately measure and compare these characteristics are required [38]. Another critical aspect of the SiC devices is their ability to tolerate high temperature operation, which can be extremely valuable in aircraft applications, and this can be seen in [27], specifically in a 540V HVDC to 28V LVDC bridge converter.…”
