With the trend to be smaller, more integration and higher power in power electronic technology, the cooling problem has become increasingly prominent for those high power devices. Micro-channel in substrate, as an effective cooling method, has been proposed and investigated by many researchers in recent years. Warpage and stress, naturally existing in all the packaging processes due to the unavoidable...

The problem of heat dissipation of high power electronics such as IGBT (Insulated Gate Bipolar Transistors) has puzzled us for long time. If the heat generated from the chips could not be eliminated away from the devices, the failure rate would rise rapidly. To deal with this problem, the micro pumps along with the microchannel embedded in the DBC substrate are proposed to remove the heat actively...
High power electronic modules, such as IGBT modules, are required in many applications, like the high speed train, solar energy inverter, CNC, frequency-alterable air-conditioner, etc. When a module works, a lot of heat would be generated due to the small size. If the heat could not be removed from the module, the high heat flux might lead to failure of the module. Therefore, a good thermal management...
With the advance of power electronic technology, HVDC light transmission based on voltage-source IGBT power converters have been increased rapidly in renewable and electric power system applications. This paper focuses on the analysis of traditional decoupled d-q vector control approaches for control of power transmission in a HVDC light system. The paper presents steady-state and transient models...
With the advance of power electronic technology, the application of HVdc light systems based on voltage-source insulated gate bipolar transistor (IGBT) converters has increased rapidly in renewable, microgrid, and electric power systems. This paper proposes an optimal control strategy for an HVdc light system using a direct current vector control mechanism. The proposed approach is compared with the...
