Applied Energy Laboratory offers a wide range of industrial projects for students in the fields of Electrical Engineering and Computer Science. Designed to bridge theory and practice, the projects challenge students to apply their academic knowledge to real-world engineering problems, encouraging innovation, teamwork, and independent thinking:
Test Design of Frequency Bounded IWPT Systems under Sub-Resonant Control for Improved Misalignment Tolerance
Supervisor(s):
Andrey Vulfovich
2024
There exist numerous cases in which wireless power transfer (WPT) systems are required to operate with varying geometrical positioning (vertical distance, misalignment) between the transmitter and receiver sides, creating the need for robust systems that can operate over a range of coupling coefficients. Subresonant frequency controlled inductive WPT link (IWPTL), utilizing frequency variation to control system output, has proven to be an effective solution to this problem, however, frequency constraints introduced in practical applications such as the SAEJ2954 electrical vehicle (EV) charging protocol naturally limit the coupling variance range for which such a system can correctly operate.

Test Application of an Active DC Link to Commercial LED Driver
Supervisor(s):
Pavel Strajnikov
2025
This paper explores practical implementation of an active decoupling device integrated into a commercial 120-watt LED driver. The device, employing a series-stacked buffer (SSB)–active DC link, replaces the traditional DC-bus electrolytic capacitor. Utilizing an auxiliary total capacitance smaller than a third of the original capacitance, the device effectively emulates the low-frequency characteristics of a
significantly larger capacitance.
The central objective of this study is to showcase the feasibility of incorporating small electrolytic auxiliary capacitors instead of ceramic class two capacitors and to design a high-power-density, compact electronic board capable of effectively replacing a large electrolytic capacitor. It is essential to note that the objective was not to optimize the physical size or cost of the proposed device but to emphasize its ability to operate identically or even improve the performance of a commercial product.

Test Optimal Load Type for Passive Magnetic Energy Harvesters
Supervisor(s):
Moshe Shvartsas
2025
MPL comparison of a passive magnetic energy harvesting under voltage-type and resistance-type loads was carried out in the brief. It was demonstrated (both analytically and experimentally) that voltagetype loading should be favored if harvested power maximization under a wide range of primary current magnitudes is targeted.

Minimum DC Link Capacitance for a Family of Three-Phase Three-Level Grid-Connected Converters Operating with Arbitrary Power Factor
Supervisor(s):
Yarden Siton
2024
This project introduces an approach to calculating the minimum value of split DC link capacitance in three-phase three-level grid-connected DC-AC converters operating with arbitrary power factor without either active balancing circuits or AC zero sequence injection. Due to the fact that partial DC link voltages and rectified mains phase voltages reach their maximum and minimum values, respectively, at different time instants, it is feasible to decrease the minimum value of the former below the maximum value of the latter while still maintaining proper functionality of the power stage. The minimum possible split DC link capacitance values are hence derived from the boundary condition where the abovementioned voltages are tangent to each other.
