“…A significant amount of research effort has been invested during recent years in the development of improved cooling technology based on various combinations of heat pipes, evaporative cooling [59], circulating coolant, forced-air, and natural-air convection cooling. The choice of a particular cooling approach is typically decided on the basis of system issues that depend on the specific rail vehicle requirements.…”

This paper presents a review of the state of the art of power electronics technology in both industrial and traction drive application. Key development trends include the dominance of ac adjustable-speed drives in new applications, with the squirrel-cage induction machine as the preferred machine in most cases. Particularly striking has been the rapid ascendance of the insulated-gate bipolar transistor (IGBT) as the predominant power switch in both industrial and traction applications ranging from fractional kilowatts to multimegawatts. Key current issues such as industrial drive input power quality and the effects of fast IGBT switching transients on the machines and electromagnetic interference (EMI) production are reviewed. Recent developments in electric traction for both rail and road vehicles are discussed, including the increasing modularity of new traction inverters in all sizes and the market introduction of new hybrid vehicles using advanced power electronics.The paper concludes with a discussion of expected future trends in power electronics technology that will likely expand the markets for industrial and traction drives during coming years.

 This paper presents a two-phase cooling method using R134a refrigerant to dissipate the heat energy (loss) generated by power electronics (PE) such as those associated with rectifiers, converters, and inverters for a specific application in hybrid-electric vehicles (HEVs). The cooling method involves submerging PE devices in an R134a bath, which limits the junction temperature of PE devices while conserving weight and volume of the heat sink without sacrificing equipment reliability.First, experimental tests that included an extended soak for more than 300 days were performed on a submerged IGBT and gate-controller card to study dielectric characteristics, deterioration effects, and heat flux capability of R134a. Results from these tests illustrate that R134a has high dielectric characteristics, no deterioration on electrical components, and a heat flux of 114 W/cm 2 for the experimental configuration. Second, experimental tests that included simultaneous operation with a mock automotive air-conditioner (A/C) system were performed on the same IGBT and gate controller card. Data extrapolation from these tests determined that a typical automotive A/C system has more than sufficient cooling capacity to cool a typical 30 kW traction inverter.Last, a discussion and simulation of active cooling of the IGBT junction layer with R134a refrigerant is given. This technique will drastically increase the forward current ratings and reliability of the PE device.

Based on the structure parameter and operating principle of the cooling system of traction converter for CRH3 high-speed electric multiple units (EMUs), a finite element model of air heat exchanger is built. Then the simulation including temperature field and fluid field is done. In order to verify the ability of the cooling system, a thermal capacity test rig for the traction converter is built. With the test rig, the temperature rise of traction converter and supply air volume of cooling system are measured in Wu-Guang high speed railway. The results show that when the high speed EMUs running in high speed, the supply air volume of cooling system will decrease, and the cooling system of traction converter for CRH3 EMUs can meet the requirement when the train continuous running in 330km/h. The simulated results are verified by the test results. The test and investigation on the thermal capacity of traction converter for high speed EMUs are firstly developed in china which makes a contribution to the design of the new generation high speed EMUs.
