Abstract :
At present, based on the piecewise linear inductance model, the main method for analytic calculation of phase current on switched reluctance generators is flux-linkage divided by inductance, and there is no analysis and deduction in detail on base of the obtained expressions of phase current. Expressions of phase current are solved by the separation variable method, and then the characteristics of current curve and the energy conversion relations are analysed in the paper. Also expressions of phase current are applied to the decision condition of current tendency and the analysis on magnetic field energy in the freewheeling mode. And a method to optimize the firing angle is proposed to get the most average electromagnetic torque. The results of simulation validate the theory in the paper and show that the theory is also applicable to the non-linear inductance model.
