METHOD FOR ACTUATING A BLDC MOTOR
A method for actuating a BLDC motor for reducing the current ripple in an intermediate circuit capacitor includes means for monitoring pulse width modulated signals (PWMU, PWMV, PWMW) for each motor phase (U, V, W), which add motor phase currents Iu, Iv, Iw) of two adjacent phases in a first step, a...

| description | A method for actuating a BLDC motor for reducing the current ripple in an intermediate circuit capacitor includes means for monitoring pulse width modulated signals (PWMU, PWMV, PWMW) for each motor phase (U, V, W), which add motor phase currents Iu, Iv, Iw) of two adjacent phases in a first step, and add the respective pulse width modulated signals (PWMU, PWMV, PWMW) if the added currents 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 added signals result is greater than 1. |
