Abstract
A power supply control circuit of a three-phase brushless DC (BLDC) motor is provided. The control circuit includes means for calculating the DC current consumption Ibased on a phase current signal Iof the BLDC motor, the means including a shunt resistor R, an amplifier and a low pass filter. The amplifier is configured to amplify a measured voltage Vthat corresponds to the current Iacross the resistor Rand perform an offset correction. The low pass filter is configured to provide a filtered voltage Vof the voltage V. The DC current Iis calculated based on the voltage V.
