“…Therefore, the PWM strategy for the SiC inverter is also aimed to achieve the high efficiency of the SiC inverter. The existing PWM strategy used in the propulsion inverter guarantees maximizing the efficiency of the SiC inverter [14]. This strategy uses not only linear voltage modulation but also over-voltage modulation and six-step modulation.…”

“…Nowadays, the PMSMs have become attractive for railway operation company to save the operating cost. Along with the interest in PMSMs, the research on the PMSM drive control has been introduced in many paper [11][12][13][14][15][16][17][18]. The research theme in the railway vehicle can be divided into several areas: torque control, sensorless control, restarting control, and fault tolerant control.…”

This paper suggests the reasonable switching frequency determination method for achieving highest efficiency of the railway propulsion system consisting the silicon carbide (SiC) inverter and permanent magnet synchronous motor (PMSM). The SiC power device allows increasing the switching frequency of the inverter because it has the small switching power loss. The total efficiency is taken into account for determining the switching frequency of SiC inverter in this paper. In the efficiency analysis of SiC inverter and PMSM, the PMSM drive control is considered with the hybrid switching method combined the synchronous PWM and asynchronous PWM. The result of the analysis shows the efficiency curve of propulsion system depending on the switching frequency. The switching frequency having the minimum power loss of propulsion system is selected based on the extracted power loss curve.

“…In the propulsion inverter of a railway system, the one-pulse switching method has been used in a wide operation range of induction motors [4,8]. The one-pulse switching method leads to a large torque ripple, which generates more vibration in a railway train than that using a carrier-based pulse-width modulation (PWM) method.…”

“…Most of them are based on electric railway systems that are an eco-friendlier system when compared to traditional diesel railway systems. Therefore, the propulsion system of an electric railway consists of a power conversion converter and electric motor [1][2][3][4]. At first, DC motors were used for railway systems, however, as technology advances, three-phase induction motors driven by a conventional two-level inverter with insulated gate bipolar mode transistor (IGBT) modules have replaced them [5][6][7].…”

In this paper, the effect of the heat-pipe cooling system design processes on the reliability of the power module in a railway propulsion inverter was investigated. The existing design processes for the heat-pipe cooling system guarantee that the junction temperature of power devices does not exceed the maximum allowable junction temperature when the railway propulsion inverter operates under its mission profile; therefore, each step of the design process was reviewed to analyze the effect of the heat-pipe cooling system. Based on the processes, in the calculation for the required thermal resistance of the heat-pipe cooling system, two difference losses were considered with the thermal resistances of the insulated gate bipolar mode transistor (IGBT) module and the thermal grease at an interface between the baseplate of IGBT module and heat-pipe cooling system. The control scheme and mission profile of the train were taken into account to calculate the power losses. Then, the designed heat-pipe cooling systems were compared in terms of the size and weight. In addition, the junction temperatures and lifetimes of the power module with heat-pipe cooling systems designed by different power losses were estimated and compared. Finally, guidelines for a heat-pipe system cooling design are proposed.
