This paper presents the results of investigations impact parabolic pulsed heating on output voltage levels a thermoelectric generator. The experiment was set up and tested under different test conditions. were investigated. experimental showed that applying 40, 60, 80 100 °C significantly maintained generator at about 80-95% which from steady case 10-30% maximum level. Moreover, pulse technique...

Temperature sensitive electrical parameters (TSEP) provide an indirect and noninvasive method for on-line junction temperature estimation of power semiconductor devices. It is known that the fundamental TSEP-based methods to calibrate relationship between TSEP in advance. However, calibration literature need open module, require pretesting, or record operating data a converter entire rating ran...

Solder degradation is still a main failure mechanism for power semiconductor modules. This study proposes monitoring method to detect the relative change in heat dissipation from module two opposing directions, affected by degradation—upward via silicone gel and downward solder layer heatsink. The based on external package measurements, condition indicator <inline-formula xmlns:mml="http://www....

Environmental concerns and energy efficiency have been driving the transportation innovation in past decades. In this framework, hybrid city transport has receiving attention of industry. The challenges for application are required high-power density, lower maintenance cost high-temperature environment due to integration with internal combustion engine. A multiport converter is proposed realise...

Lithium-ion batteries are widely used in the electronics industry to store electrical energy. One of challenges with these is that they heat up during operation, which can damage battery. For this reason, paper simulates cooling process a plate-type (BTP) lithium-ion battery pack. To control temperature (T-B), laminar air flow and phase change material (PCM) used. The PCM placed sink around Thi...
