Recently, the thermal management of power electronic converters has gained significant attention due to the continuous trend of developing very compact power electronic converters with high power density. With the evolution of power semiconductor devices, high operating temperatures and large thermal cycles have become possible, necessitating a significant improvement in thermal system designs. Researchers have made significant efforts to develop effective thermal management systems for improving the reliability and lifetime of power electronic converters. This article intends to present a thorough review of thermal management systems employed in power electronics cooling. The applied thermal management techniques have been reviewed from the perspective of electrical parameter regulation and heat dissipation control. Regulation of electrical parameters involves active thermal control, which is a method for controlling junction temperature and thermal cycling of power semiconductor devices. The active thermal control implementation processes reviewed in this article consist of increasing overload capacity, manipulating switching and conduction losses, employing modified modulation process, balancing thermal stress at the converter level, and controlling thermal stress at the system level. Control of heat dissipation can be achieved through direct and indirect cooling of power electronic converters with air or liquid as the coolant. The effectiveness and implementation methods of these cooling techniques, such as channel cooling, phase change material-based cooling, immersion cooling, jet impingement and spray cooling, are reviewed in this paper. Moreover, performance-enhancing ideas and challenges for these techniques are discussed. The primary objective of this review paper is to bridge the existing gap in the literature by offering a comprehensive comparison of commonly employed thermal management techniques.

Power converters have widespread applications in automotive, renewables, and power systems. The demand for power modules with low power consumption and high efficiency has increased due to advancements in semiconductor devices. So, power converters need to be highly efficient to reduce costs associated with energy dissipation and cooling requirements. This paper discusses various active thermal control methods for high-power power converters. It covers modulation and configuration techniques, ranging from single configurations to cascaded, modular, and multilevel converters. These concepts form the basis of power electronics building blocks, particularly relevant in all-electric ship systems. Power electronics building blocks represent a This article has been accepted for publication in IEEE Access.

“…Since the measured values are available at high sample rate in the FPGA, adapted signal preprocessing can be implemented, which relieves the further signal processing in the control. Based on the simple example, other measurement and inverter or converter configurations of any complexity can be implemented easily and quickly [10,13,14].…”

In this paper a highly performant modular and fully adaptable real-time signal processing platform is introduced, which can be used to control all kinds of applications in the field of power electronics and electrical drive control, such as Hardware-in-the-Loop (HIL) systems, Power Hardware-in-the-Loop (PHIL) systems and power electronic systems for grid and drive applications. The proposed system was fully developed and built in the ETI, enabling full access to even the last register inside the FPGA and the whole software architecture. Another benefit of the in-house production is, that the costs are very low compared to proprietary system on the market and hence every researcher in the ETI has access to it. With this highperformance real-time signal processing platform, it is possible to push high performance research topics in the field of power electronics and electrical drive control forward.
