This paper deals with a comparative evaluation of the single-phase “VIENNA I” and the “DBE” rectifiers. Their cores respectively involve one and two coils. They operate in continuous current and PFC modes thanks to an AC side current control. The two coils allow to get a “Double Boost Effect” during each half-period(More)
This paper deals with Torque Control Strategy of non-sinusoidal Brushless DC Motor based on fractional regulator. In this case, the dq components of the EMF are not constants. Then, the optimisation of the torque and the reduction of copper losses and torque ripples need to synthesize and to impose an optimal current waveform in dq frame. Also, the current(More)
This papar deals with an optimal control of 5-Phase Vienna rectifier - PMSG set for Marine Current Turbine Applications. In order to optimize the transfert of the power all EMF harmonic are exploited. Then the control strategy needs to impose optimal current waveforms under normal operation and under fault operation. These current references are not(More)
This paper proposes a modeling procedure of synchronous machine with admittance networks. Load and stator are modeled in a conventional way, i.e. in dq frame. The accent is given to inaccessible parts of the machine (rotor). Hence, the rotorpsilas circuit is modeled with admittance functions. The order of the system, which depends on the desired precision,(More)
This paper deals with controls of a converter, where two paralleled-inverters are used. One inverter acts as a master unit and the other one acts as a slave unit. Thanks to these controls, an accurate tracking of the references is got and the output voltage ripples are lowered. As the goal is not to expand the system capacity, the slave unit delivers the(More)
