    • A system and method for providing an interface between a master device referenced at a first voltage and a slave device referenced at a second voltage. The system includes a bidirectional communications link between the master device and the slave device and a bidirectional transceiver device in the communications link for decomposing bidirectional signals on the communications link into transmissions from the slave device to the master device onto a first bus, and transmissions from the master device to the slave device onto a second bus. A first isolation device is included in the bidirectional link and connected to the first bus for transmitting signals over the bidirectional link from the master device referenced at the first voltage to the slave device referenced at the second voltage. A second isolation device in also included in the bidirectional link and connected to the second bus for transmitting signals over the bidirectional link from the slave device referenced at the second voltage to the master device referenced at the first voltage.

    • A system and a method for starting a brushless DC motor are provided. The method includes applying commutation pulses to at least two phase coils to induce a rotor to rotate to a starting position and then de-energizing the at least two phase coils. The method further includes applying commutation pulses to at least two phase coils to induce the rotor to rotate from the starting position in a predetermined direction. The method further includes de-energizing all phase coils for a first time interval after the rotor is rotating and sampling a back EMF signal in at least one of the phase coils to determine a first value indicative of an electrical period of the back EMF signal or a portion of an electrical period of the back EMF signal. Finally, the method includes applying commutation pulses to at least two phase coils for a second time interval, the second time interval being based on the first value.
    • 提供了一种启动无刷直流电动机的系统和方法。 该方法包括将换向脉冲施加到至少两个相位线圈以引起转子旋转到起始位置,然后使至少两个相位线圈断电。 该方法还包括将换向脉冲施加到至少两个相位线圈以引导转子沿预定方向从起始位置旋转。 该方法还包括在转子旋转之后的第一时间间隔内使所有相线圈断电,并在至少一个相位线圈中采样反电动势信号,以确定表示反电动势信号的电周期的第一值,或 反电动势信号的电气周期的一部分。 最后,该方法包括对第二时间间隔的至少两个相位线圈施加换向脉冲,第二时间间隔基于第一值。
