In this article, a novel single-stage transformerless buck–boost inverter is introduced. The proposed inverter can share a common ground between the DC input side and the grid; this leads to having a zero-leakage current. The proposed inverter also provides the buck and boost voltage capabilities. Additionally, the power switches are operated at high frequency in the half-cycle of the sinusoidal wave, so the efficiency of the proposed inverter can be improved. Operating analysis, design consideration, comparison, and simulation study are presented. Finally, a 500 W laboratory prototype is also built to confirm the correctness and feasibility of the proposed inverter.

Recently, the stability of DC microgrids has attracted increasing attention. The traditional stability analysis method cannot not meet the requirements for the complexity and bidirectional energy flow of the system. In this paper, a passivity-based stability criterion (PBSC) is proposed to analyze the stability of the cascade system. In order to realize the passivity of the system, an improved feedback control method based on the traditional double-loop control strategy is proposed, which will improve the stability region and guarantee the passivity of the system. Moreover, a Buck-CPL simulation model is established based on MATLAB/Simulink R2008, and the correctness of the theoretical analysis is verified by experiments.

“…Volumetric thermal resistance is a parameter of a value selected based on the available cooling air speed according to Table 1 [106]. For heat sinks of a volume smaller than 300 cm 3 , it is recommended to use a lower limit of R V , while for large heat sinks greater than 1000 cm 3 , the upper limit should be used. Designing is an iterative process and the selected R V value may be fine-tuned based on the heat sink volume obtained in the previous iteration.…”

In this paper, a detailed review of contemporary cooling systems of semiconductor devices is presented. The construction and the principles of operation of selected components of passive and active cooling systems, as well as selected computer tools supporting the design of such systems, are described. The dependences of thermal parameters calculated using these tools on selected factors characterizing the used cooling systems, e.g., the dimensions of their components, are presented and discussed. Additionally, some results of measurements illustrating the influence of selected parameters on the thermal resistance of power MOSFETs mounted in different cooling systems are shown. The properties of selected cooling systems are compared, and it is shown that by changing the type of cooling system, it is possible to reduce the thermal resistance value of a power MOSFET even 20 times. The presented considerations can make the process of designing cooling systems more effective.
