This paper presents a pre-sizing approach of DC-DC converters. This approach can be carried out in two main steps. The first step consists on determining the most adapted architecture to answer the specifications and the appropriate technologies of the passive and the active components of the selected architecture by considering major constraints (volume, cost…). The technology choice is carried out using models developed from manufacturer datasheets. The second step consists on optimizing the selected architecture by considering the appropriate technologies resulting from the first step under multi-physic constraints: thermal, losses (or efficiency), volume …. The proposed approach allows reducing significantly the computing time which is suitable in a pre-sizing phase where several parameters must be optimized and multi-physic constraints must be respected.

In this paper, a digital repetitive control strategy is proposed to achieve zero tracking error for Power Electronic Load Simulator (PELS). The proposed control scheme is of “plug-in” structure: a plug-in digital repetitive controller plus a conventional controller (e.g., P or PD controller). The design of the plug-in repetitive learning controller is systematically developed. The stability analysis of overall system is discussed. A repetitive controlled PELS is given as an application example. Desired current can be ensured under parameter uncertainties and disturbances. Simulation results are provided to testify the effectiveness of the proposed control scheme.

This paper is concerning a new impedance matching control used in the plasma processing. RF electricity is supplied to the plasma chamber and stability operation is required. For this purpose the impedance of the equivalent loads is controlled to be 50 [Ω]. Therefore the capacitance of capacitors in an LC circuit called a matching box is adjusted and the receiving end impedance is maintained to be 50 [Ω]. In this paper a novel control method of an impedance matching is proposed and the successful experimental results are presented.

With the progress of science and technology, a new generation of IGBT/IGCT power electronics module with good performance is developing rapidly with successful commercialization and serialization, gradually replacing the old power electronic devices in the range of medium-capacity. Therefore, the same type of HVIGBT should be adopted substitute for original GTO and corresponding domestic development is very necessary. Novel development work of GTO auxiliary system replacing by HVIGBT choppers and inverters have been carried out and completed in 2006. The new system is in reliable operation on line1 vehicles for more than 2 years. After analyzing the original GTO Auxiliary System, simulation on novel HVIGBT chopper for the system is given in this paper. Compared with the simulation results, experimental waveform based on the newly developed HVIGBT chopper which is composed of 800A /3300V HVIGBT module is consistent on the whole. The rating capacity of the HVIGBT chopper is 80kVA and the instantaneous overloaded capacity is 120kVA.Two years' practice has proved that the novel development of static auxiliary system, which has the advantages of small loss, high efficiency and high reliability, is an effective measure for ensuring Shanghai Line 1 vehicles continued reliable operation.

An improved space vector modulation (SVM) approach for matrix converter (MC) operation in unbalanced and non-sinusoidal input voltage condition was presented. The concept of modulation vector was introduced, and the relationship of output voltage and input voltage of MC by space vector denotation was deduced. Using the modulation vector approach, an improved SVM approach was proposed to improve the output performance of MC in abnormal input voltage conditions. The novel approach was based on dynamic control of the output voltage modulation vector respect to the instantaneous input voltage vector. By this method, the unbalanced and non-sinusoidal input voltages could be automatically compensated without any extra calculation so the output voltage could keep balanced and sinusoidal in expected value. The validity of the improved SVM approach was verified by simulation and experiments.

A new approach to design LPV robust gain scheduling controllers for a variable pitch variable speed wind turbine drive system is presented. The time-varying nonlinear model of the wind turbine is translated into a linear parameter varying (LPV) system with convex polyhedron version via the LPV convex decomposition technique. State feedback controller satisfying H∞ performance at every vertex of convex polyhedron parameter space can be numerically solved via linear matrix inequalities (LMI) approach. Using these designed controllers at every vertex, a LPV controller with smaller on-line calculating capacity is synthesized via convex decomposition techniques. Simulation results show better tracking performances and disturbance rejection abilities of the proposed controller than.

Variable speed operation of wind turbines presents certain advantages over constant speed operation. Reliable and powerful control strategies are needed for wind energy conversion systems to achieve maximum performance. This paper stated two control strategies for variable speed operation, include Speed-mode control and Torque-mode control. Maximum power tracking and power fluctuation will be analysed when exciting the different configurations with a particular wind profile. Simulation results by using actual detailed parameters for wind turbine show the effectiveness and robustness of this control Strategy.

An improved predictive current control through parameter estimation is presented. The future value of grid current is predicted by a discrete-time model. The predicted value of grid current is evaluated by the quality function. The optimal switching state that minimizes the quality function is selected. The predictive current control is sensitive to variations in parameters. The effect of variations in parameter values on control system is compensated by parameter estimation. The parameter estimation is achieved by the least square method. The estimated parameters are applied to predictive model and it improves an accuracy of control system.

The operation principle of bearingless induction motor was introduced, and then the mathematical equation of the radial force model for the bearingless induction motor with conventional 4-pole stator windings and additional 2-pole windings was transformed. A decoupling control method named as neural network inverse system (NNIS) was presented for the radial suspending model of bearingless induction motor. Aimed at the nonlinear and strongly coupled characteristics, the model is analyzed with reversibility and proved to be reversible. The multi variable, strongly coupled, nonlinear system was dynamic decoupled into two linear displacement subsystems by connecting a NNIS before the bearingless induction motor. Then the two decoupled linear subsystems were synthesized under the help of lineal closed-loop controllers. The simulation test results show that independent control on two degrees of freedom of radial position for the bearingless induction motor can be realized through NNIS method and the dynamic and static performance of the closed loop system designed is satisfactory.
