“…Clearly, when the TEMs operate in similar conditions, the voltages and the internal resistances of all modules are the same. Therefore, the power obtained by ( 6) and (7) will have the same value, i.e. the electrical connection of the TEMs does not affect the total output power [32].…”

A considerable part of the fuel energy in vehicles never reaches the wheels and entirely converts to waste heat. In a heavy duty vehicle (HDV) the heat power that escapes from the exhaust system may reach 170 kW. The waste heat can be converted into useful electrical power using thermoelectric generator (TEG). During the last decades, many studies on the electrical power conditioning system of TEGs have been conducted. However, there is a lack of studies evaluating the electrical instrumentation, the impact of the converter-efficiency, and the TEG arrangement on a real large-scale TEG on-board a drivable vehicle. In this study, the most important parameters for designing electrical power conditioning systems for two TEGs, developed for a real-scale HDV as well as experimental results demonstrating the recovered electrical power, are presented. Eight synchronous inter-leaved step-down converters with 98 % efficiency with perturb and observe maximum power point tracker was developed and tested for this purpose. The power conditioning system was communicating with the on-board computers through the controller area network and reported the status of the TEGs and the recovered electrical power. The maximum recovered electrical power from the TEGs reached 1 kW which was transmitted to the electrical system of the vehicle, relieving the internal combustion engine.

“…This is a clear advantage of TEG systems, since it produces smaller payback periods -compensating so the disadvantage of using over dimensioned inverters. A useful example on interfacing Seebeck elements to helicopter electric networks can be found in [22,23].…”

This paper presents two different approaches for the incorporation of commercial inverters in ships' low voltage electric network, either for the exploitation of renewable sources such as the sun and the wind, or for energy regeneration from the exhaust gases heat. Both solutions contribute to the reduction of CO2 emissions as well as to fuel consumption reduction. The inverters as well as all the necessary installation components should meet the requirements for Safety of Life at Sea (SOLAS) as they are reported on IEC 60092 or IEEE 45 series and are a part of ABS rules -approved from national and international register of shipping organizations.

“…With the development of new energy storage technology such as flywheel, superconductor, super capacitor, energy feedback technology based on energy storage device with super capacitor is widely used in the control of elevator energy saving [6][7][8][9][10][11][12][13][14]. Aiming at the shortcoming of fluctuation regenerative energy affects the power quality in energy feedback power grid, [6] proposes grid power optimization control to reduce the fluctuation of power grid and improve the power quality.…”

“…The method of traffic flow difference was introduced in [7] to determine the capacity of the super capacitor in elevator energy storage, and the control strategy under different energy state is studied. The structure and control strategy of super capacitor energy storage for elevator is analyzed in [8][9][10][11]. For imbalanced voltage of single capacitor, super capacitor voltage balancing strategy is proposed in [12] to prevent the voltage unbalance of influence system safety.…”

To improve the overall efficiency of modern building elevator, an active regenerative braking converter using a bidirectional Buck-Boost converter is implemented. The converter is connected in parallel to the inverter DC-bus. Energy is stored in a set of super capacitors during regeneration and it is transferred back to the DC-bus when the elevator accelerates. The control strategy of the storage system with super capacitors is proposed. In order to validate the effectiveness of the proposed method, the simulation model of the elevator system has been built up. Simulation results show that the control strategy can achieve recycling and reuse of regenerative energy in traction elevator.
