  • This paper gives a description of the mode'ling and control of a single phase PWM(Pulse Width Modulation) converter for HEMU-400X(High-speed Electric Multiple Unit - 400 km/h experiment). The converter is part of a Auxiliary power unit supplied by the 25[kV], 60[Hz] overhead line. A model of the converter in a synchronously rotating reference frame of coordinates is used to develop a new type of control. The control system has separate controllers for the active and reactive current, permitting the free choice of the power factor. This paper proposes a new control method of PWM converter for Auxiliary power unit.

  • The single-phase PWM converter employing power semiconductors is currently applied to the power unit of high-speed rail vehicle and increasingly used as the front-end converter with properties of near unity power factor. Power factor and harmonics are increasingly important needs for drive system of high-speed rail vehicle. The proposed approach has many advantages which include fewer semiconductor components, simplified control, high performance features and satisfies IEC 555 harmonic current standards. Simulation results show that the dc-link voltage control obey the reference value during constant load and input current is near sinusoidal.

  • For the research, we developed the hardware and software of the measurement system for on-line test and evaluation. The software controls the hardware of the measurement data and acts as a interface between users and the system hardware. In this paper, we studied performances of the auxiliary block for high-speed railway vehicle. In order to performance these works, the conversion system was developed. Using this system, we obtained the important results, such as voltage values for the battery charger and auxiliary block. Also, we diagnosed the faults and performed the evaluation for auxiliary block using the measurement system and data.

  • In recent years, the interest in noise increases gradually and the low noise level becomes one of the important performances in electrical equipment for railway vehicle. In the auxiliary power supply, most of the noise is made by the current ripple of alternating current reactor(ACL) which filters the output voltage. And this current ripple results from the voltage harmonics across the ACL. So the noise can be reduced by eliminating the voltage harmonics across the ACL. This paper shows harmonic eliminating technique which is making gating signals of upper and lower inverter have a phase difference in the 12-step inverter type auxiliary power supply. This technique was proved by testing on the developed 180KVA auxiliary power supply using IGBT.

  • To reduce harmonics in the AC line and achieve a unit power factor, A 4 paralled single phase PWM AC/DC converter has been proposed. In this paper, the coupling components are derived analytically from PWM converter input transformer model and control scheme to solve this problem is proposed. Unit power factor was obtained and the AC-side current harmonics were reduced. Simulation results show the usefulness of the proposed method and applicability to PWM converter in auxiliary block of high speed train.

  • The static inverter is mainly used to provide with the electric power of various loads in the train. In the recent european projects, the specification of static inverter become harder, and many additional service function is expected. It takes long time and high cost to develope a static inverter with these high performances and additional function. But, these are became general demands for static inverter in the many projects from now on. The APSE(Auxiliary Power Supply Equipment) is a static inverter of high performance to satisfy the severe specification and various service function following these tendency for Athens project In this paper, the specification of APSE and various service functions are introduced to look about current tendencies of static inverter.

  • In this paper, the charge control with the input voltage feedback is proposed for the input series-output series-output parallel connected converter configuration for the high speed train power system application. This control scheme accomplishes the output current sharing for the output-parallel connected modules as well as the input voltage sharing for the input series connected modules for all operating conditions including the transients. It also offers the robustness for the input voltage sharing control according to the component value mismatches among the modules. And this configuration enables the usage of MOSFET for a high voltage system allowing a higher switching frequency for lighter system weight and smaller size. The performance of the proposed scheme is verified through the experimental results.

  • The railway vehicle has an auxiliary power unit for supplying power to the associated electronic control devices and passenger service unit. Typically, input voltage from the catenary for rolling stock is highly fluctuating according to the substation capacity, vehicle propulsion and regeneration. Especially, the frost and freezing on contact wire in winter can cause a blackout inside vehicle, and also brings about electronic components damaging and the system down. To prevent this problem, a large filter and capacitor is used. But this is not a perfect solution, because it is increasing weight of the unit. In this paper, a new algorithm is proposed to suppress the disturbance without adding devices. Simulation and experimental results show that the proposed algorithm has performance to suppress the disturbance at the sudden input voltage variations.
