Abstract: The present invention is a brushless dc motor driver system for quiet commutation of current from one load winding to another load winding. The system comprises a first circuit, a second circuit and a third circuit. Each circuit comprises an upper field effect transistor connected at one end to a voltage source and at its other end to a junction of a corresponding lower field effect transistor and a load. The system further comprises a resistor electrically connected to each lower transistor. The resistor generates a signal representative of the total current of the three circuits. The system also comprises a pulse width modulator electrically connected to each field effect transistor. The modulator controls the commutation system. The modulator comprises a comparing means, a responsive means, a gate slew and a determining means.
