“…With the goal of reducing the size of the converter, a BBC with coupled inductors (BBC-CI) was proposed in [14], wherein the inductors of the boost and buck cells were negatively coupled via a common magnetic core. The topologies of the BBC and BBC-CI are shown in Fig.…”

A dual-input boost-buck converter with coupled inductors (DIBBC-CI) is proposed as a thermoelectric generator (TEG) power conditioner with a wide input voltage range. The DIBBC-CI is built by cascading two boost cells and a buck cell with shared inverse coupled filter inductors. Low current ripple on both sides of the TEG and the battery are achieved. Reduced size and power losses of the filter inductors are benefited from the DC magnetic flux cancellation in the inductor core, leading to high efficiency and high power density. The operational principle, impact of coupled inductors, and design considerations for the proposed converter are analyzed in detail. Distributed maximum power point tracking, battery charging, and output control are implemented using a competitive logic to ensure seamless switching among operational modes. Both the simulation and experimental results verify the feasibility of the proposed topology and control.

“…Therefore, the rate of the thermoelectric energy conversion may be reduced [11]. In order to increase the conversion rate around this temperature range, liquid cooling instead of air (fan) cooling could be a solution to reduce the rate of extraneous heat dissipation through the air [13,23,24]. Moreover, the electrical and thermal losses likely also contribute to this discrepancy since, in reality, a perfect contact between layers (Fig.…”

The increasing integration of high performance processors and dense circuits in current computing devices has produced high heat flux in localized areas (hot spots) that limits their performance and reliability. To control the hot spots on a CPU, many researchers have focused on active cooling methods such as thermoelectric coolers (TECs) to avoid thermal emergencies. This paper presents the optimized thermoelectric modules on top of the CPU combined with a conventional air-cooling device to reduce the hot spot temperature and at the same time harvest waste heat energy generated by the CPU. To control the temperature of the hot spots, we attach small-sized TECs to the CPU and use thermoelectric generators (TEGs) placed on the rest of the CPU to convert waste heat energy into electricity. This study investigates design alternatives with an analytical model considering the non-uniform temperature distribution based on two-node thermal networks. The results indicate that we are able to attain more energy from the TEGs than energy consumption for running the TECs. In other words, we can allow the harvested heat energy to be reused to power other components and reduce hot spots simultaneously. Overall, the idea of simultaneous hot spot cooling and waste heat harvesting using thermoelectric modules on a CPU is a promising method to control the problem of heat generation and to reduce energy consumption in a computing device.

“…Free availability of heat makes harvesting energy from it as one of the most viable sources of electricity [2,3]. Thermoelectric Generators (TEGs) directly convert heat into electrical energy based on the Seebeck effect [4][5][6]. TEGs have gained considerable attention [7] due to their noiseless operation, stability and absence of moving parts thus providing high reliability and facilitating their implementation [8,9].…”
