Online open-switch fault diagnosis method in single-phase PWM rectifiers PROJECT TITLE :Online open-switch fault diagnosis method in single-phase PWM rectifiersABSTRACT:On the idea of sampling theory, an online open-switch fault diagnosis and site method for single-section pulse-width modulation rectifiers applied in electric railway traction is presented. Initial, on the basis of analysing the options of the post-fault line current under instantaneous current control strategy at low switching frequency, 2 specific pulse sequences for sampling line current are generated via the modulation. Then, the DC component of the sampled signal, which is straightforward to use for diagnostic call, is obtained through filters. Experimental results are presented to illustrate the validity of the proposed scheme. Did you like this research project? To get this research project Guidelines, Training and Code...
