Title:
METHOD FOR ACTUATING A BLDC MOTOR
Document Type and Number:
WIPO Patent Application WO/2013/110501
Kind Code:
A3
Abstract:
The invention relates to a method for actuating a BLDC motor for reducing the current ripple in an intermediate circuit capacitor, wherein there are means for monitoring pulse width modulated signals (PWMU, PWMV, PWMW) for each motor phase (U,V,W), which add motor phase currents (lu, lv, lw) of two adjacent phases in a first step, add the respective pulse width modulated signals (PWMU, PWMV, PWMW) if the value is over zero, and shift the phase of at least one pulse width modulated signal (PWMU, PWMV, PWMW) in the time slot T if the result is greater than 1.
