Offset PWM signals for multiphase motor |
摘要 |
<p>A multi phase motor includes a switching array for interconnecting a power source to each phase. A current sensor senses current supplied from the power source via the switching array to the winding and a controller generates offset PWM signals for controlling the switching array to supply power to each of the phases of the winding.</p><p>The offset timing allows the individual phase currents to be determined from a single current sensor.
