In this paper, the ringing effect is investigated in detail. Based on the half-bridge circuit, the possible switching pattern causing the ringing effect is verified thoroughly. A high frequency switching model is derived for the linear rail gun. The equivalent circuit model is also derived to analyze the ringing effect further. Besides, the FPGA digital implementation for the current pulse control is also concentrated on to get precise timing control for the current pulse generator. By simulation and experimentation, it is shown that the ringing phenomena can be observed by way of this developed model. The current pulse is generated successfully with the digital implementation. It is believed that the associated investigation will be useful to improve the performance for the linear rail gun.","PeriodicalId":191010,"journal":{"name":"VIII IEEE International Power Electronics Congress, 2002.

By using the ringing choke converter with distributed parallel windings (DPW-RCC), the configuration will be easily expanded when the power rating is increased for the linear synchronous machine. Therefore, no further redesign work is required. The associated analysis and design for the chopper by using DPW-RCC is also provided. It is believed that the associated investigation is applicable to the associated the movable chopper design for the linear synchronous machine, especially in the high power multi-level topology for the linear synchronous machine drives. By using high frequency self-resonant switching, which is better than the low frequency switching, the required power will be easily transferred from the fixed module on the ground to the moving module without contact. Again, the high frequency switching is self-resonant based on soft switching principle. That means the associated system loss will be decreased and the entire system efficiency will be improved considerably. This paper sets up design guide for the contactless DPW-RCC structure. It is believed that the associated investigation will be helpful to design the related contactless induced movable chopper for the linear synchronous machine.","PeriodicalId":191010,"journal":{"name":"VIII IEEE International Power Electronics Congress, 2002.

Its main feature is that, besides injecting energy into the grid, it behaves as an active filter. The reference signal used to modulate the output current is obtained through an adaptive filter. The main advantages of the technique are that the system becomes almost independent of the parameter variations, and that it lends itself to a very simple hardware implementation.

It is proposed instead of the classical drive bogie system, where an inverter supplies only one motor. Moreover, four partial speed sensorless methods are applied in it. Then, a comparison between these applied operating structures in two different control strategies for parallel connected dual induction motors is presented in this paper. The system behavior comparison takes into account two internal motor parameter variations and one external perturbation. It is important to note that the system presents two important interactions. On one hand, an electrical coupling is established by the voltage inverter, which supplies both motors. On the other hand, the common load, here represented by the locomotive, is relied to the motors by the mechanical transmissions imposing a mechanical coupling. The system has been modeled using the SABER solver from Avant! Corporation.","PeriodicalId":191010,"journal":{"name":"VIII IEEE International Power Electronics Congress, 2002. Technical Proceedings.

As an example, a 6 pulses rectifier with a 35 kA DC load current have a secondary phase current given by 17.5 kA//spl radic/3 = 10.1 kA. These parameter differences produce a DC unbalance current in the interphase reactor. The effect of this is a saturation risk on the reactor and in the power transformer. As a consequence of this, noncharacteristic harmonics on AC primary winding appear. This phenomenon is analyzed in this paper. Conclusions concern how to determine the order of harmonics in primary winding due to interphase reactor unbalance. This concept of harmonic analysis of primary current is used as a diagnostic method to determine how is the interphase reactor operating. Finally, an independent current control of each secondary load currents is proposed in order to mitigate the reactor saturation.","PeriodicalId":191010,"journal":{"name":"VIII IEEE International Power Electronics Congress, 2002.
