This paper presents the methods for estimating automotive alternator's back electromotive forces without a direct mechanical sensor of the rotor position. It is shown that the back electromotive forces may be observed based on system's phase current model by sensing electrical variables of the synchronous rectifier. Experimental results are presented for validation of the proposed observation algorithms.
