    This paper presents a novel output power control method for variable-speed switched reluctance generators (SRG). In the single pulse mode, the conduction angles dictate the waveform of phase current which directly influences the output power. With the proposed method, the conduction angles can be estimated from the output power profiles at several speeds using an artificial neural network (ANN). The output power profiles are simulated from a dynamic model of an 8/6 SRG and used as the training data of the network. The inputs of the network are the output power and rotor speed, and its outputs are the turn-on and turn-off angles. The proposed control scheme was developed by incorporating the trained network into the dynamic model before the simulation in MATLAB/Simulink. The experiments with the 8/6 SRG were carried out using TMS320F2812 DSP to control the SRG drive system. In addition, the optimal trained weights and biases of the network are utilized in the DSP program. The comparisons of the simulation and experimental results are made to verify the proposed method.

    Study of maximum power conversion of a switched-reluctance generator

    This paper presents the study of maximum power conversion of a Switched Reluctance Generator (SRG). The SRG is operated in single pulse mode where the rotor speed is above base speed. The turn-on and turn-off angle are varied to study the shape of the phase current which is directly related to the power conversion. A 4 Phase, 2kW, 8/6 SRG is used to collect the experimental results. The converter is the conventional 2-switched per phase and a TMS320F2812 Digital Signal Processing (DSP) is a main controller. © 2011 IEEE.
