This paper presents the control and modeling of a wind energy system that consists of a single-switch three phase boost converter with a sensorless maximum power point tracking (MPPT) method. The single-switch three phase boost converter, which has the advantage of using one switch in the converter to achieve power factor correction for the generator output current, and is able to simplify the control...
This paper deals with a modeling approach of an embarked electrical network. This network is composed of a synchronous generator feeding linear and non linear load. In order to simplify the identification of inaccessible part of the generator, a specific modeling approach of the machine is established. Thus, the rotor is modeled by generalized transfer functions. Its order is chosen to have the desired...
In this paper we discuss performance results of a novel real-time closed-loop power amplifier (PA) linearization technique that has originally been proposed by Ahmed and Li. The novel approach performs on-the-fly prediction and measurement of the PA AM/AM and AM/PM non-linearity, stores such non-linear characteristics and calculates their inverse functions in order to pre-distort the base-band amplitude...
A high voltage drive for radiofrequency ion thrusters is proposed. The load, consisting of a heavy ion plasma, imposes severe dynamic requirements to the power converters. State space models in the discrete time are derived for the power cells of both the high voltage generators constituting the driving system. The frequency responses of the control-to-output transfer functions are reported and the...
