Furthermore, the correlation between multilevel carrier-based PWM methods and space vector PWM (SVPWM) methods is established by theoretical analysis, by which the research on multilevel PWM methods can be included in the clew of the combination of CFD. From the clew, a simplified algorithm of SKPWM method for five-level cascade multilevel inverters is presented, which is equivalent to PS-SFO-PWM method.

By the estimation of the harmonics using the proposed disturbance observer, the compensation characteristics of the AF is very much improved. The deadbeat control can provide good current regulation without the calculation time delay. The current control is achieved by controlling the intermediate voltage of the inverter output filter so that the AF output current is regulated and the pulse width of the PWM inverter is determined by the deadbeat control law. The disturbance observer is effectively and stably realized by the proposed current regulation. As a result, the total harmonics compensation characteristics is much improved.

Current sharing based upon average current method is realized through the share bus interconnecting all the paralleled modules without extra control modules. The share bus consists of only three automatically averaged signals (no matter how many modules in parallel): inverter reference, sensed load current and feedback voltage. Current sharing control is decoupled from reference synchronization control through local feedback of the averaged reference so that inertia of the system reduced greatly. As a result a fast dynamic response and an equal load current sharing capability is ensured, under linear or nonlinear load. System configuration and operation principle are presented while simulation and experiment results are given in detail.","PeriodicalId":320424,"journal":{"name":"Proceedings of the Power Conversion Conference-Osaka 2002 (Cat.

In speed sensorless vector controls of induction motors with adaptive observers, the speed identification system becomes unstable for the major part of the regenerating region. Moreover, it is pointed out that the stator resistance variation influences the speed identification. Thus, it is necessary to find an adaptive scheme which can stabilize the identification system in whole region. Although several methods have been proposed to stabilize the identification system, they discuss only on the design of the observer gain. In these cases, the following problems exist.. The design parameter is determined by trial and error. Resulting observer gain tends to violate stability of the observer. The induction motor is assumed to be at steady state. Therefore, the stabilization of the parameter identification should be improved by designs of identification laws. In this paper, to stabilize the identification system of the speed and the stator resistance, the augmented error is introduced, yielding the transfer function of an error system becomes \"I\". Next, an adaptive scheme for the speed and the stator resistance is proposed which stabilizes the identification system. Furthermore, the proposed adaptive scheme is simplified to reduce the amount of calculation. Finally, effectiveness of the proposed method is shown by experiments.","PeriodicalId":320424,"journal":{"name":"Proceedings of the Power Conversion Conference-Osaka 2002 (Cat.

To that purpose, the paper deals with modeling, analysis and implementation issues of the PLL. Derived are nonlinear and linear state-space models and a transfer function model. Operation of the PLL is also analyzed using frequency domain methods. An implementation of the PLL using a digital signal processor is described. On the basis of the derived models, two different system controllers are designed and the system transient response for the two cases is compared. The first controller is of a proportional-integral (PI) type and the second controller is minimum response time controller. It is shown how the input signal amplitude variations affect the system transient response. A solution for solving this problem is presented.","PeriodicalId":320424,"journal":{"name":"Proceedings of the Power Conversion Conference-Osaka 2002 (Cat.
