Characterization of high-voltage IGBT module degradations under PWM power cycling test at high ambient temperature
The success of the high temperature power electronic applications depends on the power device reliability. The increasing thermal demands, like in hybrid electric cars, require power devices operating at junction temperatures above their common level of 125 C. The thermal cycles generated in standard modules in such conditions induce several failure mechanisms in their package and chips. This a...
متن کاملpower system voltage stability enhancement by high side voltage control
voltage stability may be improved by various control functions. in this paper, it is shown that how high side voltage control (hivc) may be employed for this purpose. two test systems, namely a 22- bus and ieee u8-bus systems are used to demonstrate the proposed tuning strategy for hsvc control parameters.
متن کاملInvestigation of Electrical Stress in High Voltage IGBT Power Module Using Finite Element Simulations
With increase in the demand for electrical power conversion and control, new power electronic technologies are being developed rapidly. The power conversion is possible because of silicon power devices which are the most important components of any power electronic system. Among the power devices, insulated gate bipolar transistors (IGBT) are more accepted and widely used in various application...
متن کاملHigh temperature reliability of power module substrates
The thermal cycling reliability of candidate copper and aluminium power substrates has been assessed for use at temperatures exceeding 300°C peak using a combination of thermal cycling, nanoindentation and finite element modelling to understand the relative stresses and evolution of the mechanical properties. The results include the relative cycling lifetimes up to 350°C, demonstrating almost a...
متن کاملPiezoelectric transformers for a high power module
Abstract Piezoelectric transformers are mainly commercialized for a LCD back light inverter module. With regard to laptop computers, the required output power for a piezoelectric transformer is around 5 W at present, and higher power will be needed for wider displays in the near future. In addition, modules such as AC-DC adaptors or fluorescent lamps may require a higher output power of more th...
