“…Unfortunately, such high ZT values in thermoelectric cooling systems are still far behind what can soon be achieved [ 5 ]. In contrast, ZT is not the sole relevant parameter [ 6 , 9 , 10 , 11 ] in the active cooling mode. In this active cooling mode, a combination of high active cooling (high power factor PF = S 2 σ) and high passive cooling (high thermal conductivity) determines the thermoelectric cooling performance.…”

Traditional thermoelectric materials often face a trade-off between efficient power generation (high ZT) and cooling performance. Here, we explore the potential of achieving simultaneous thermoelectric power generation and cooling capability in the recently fabricated bulk ZrSeTe Janus structure using first-principles density functional theory (DFT). The layered ZrSeTe Janus structure exhibits a semimetal character with anisotropic transport properties along the in-plane and out-of-plane directions. Our DFT calculations, including the explicit calculation of relaxation time, reveal a maximum ZT of ~0.065 in the out-of-plane direction at 300 K which is one order of magnitude larger than that in the in-plane direction (ZT~0.006). Furthermore, the thermoelectric cooling performance is also investigated. The in-plane direction shows a cooling performance of 13 W/m·K and a coefficient of performance (COPmax) of ~90 with a temperature difference (ΔT) of 30 K, while the out-of-plane direction has a cooling performance of 2.5 W/m·K and COPmax of ~2.5. Thus, the out-of-plane current from the thermoelectric power generation can be utilized as an in-plane current source for active heat pumping. Consequently, we propose that the semimetal ZrSeTe Janus structure can display bifunctional thermoelectric properties for simultaneous thermoelectric power generation and active cooling.

“…Phase change materials (PCMs) can also be used to clamp the temperature for a specific duration [8]. It may also be possible to introduce Peltier elements into the package [9]. OC capability may also be enabled through control [10] of the VSI, or by temporarily reducing the switching frequency.…”

With the increase in penetration of power electronic converters in the power systems, a demand for overcurrent/overloading capability has risen for the fault clearance duration. This article gives an overview of the limiting factors and the recent technologies for the over-current performance of SiC power modules in power electronics converters. It presents the limitations produced at the power module level by packaging materials which include semiconductor chips, substrates, metallization, bonding techniques, die attach, and encapsulation materials. Specifically, technologies for over-current related temperatures in excess of 200 • C are discussed. The paper also discusses potential technologies which have been proven or may be potential candidates for improving the safe operating area. The discussed technologies are use of phase change materials below the semiconductor chip, Peltier elements, new layouts of the power modules, control and modulation techniques for converters. Special attention has been given to an overview of various potential phase change materials which can be considered for high-temperature operations.
