Abstract: Method of accelerated extinguishing of residual current of a phase that opens when changing an electric position during the driving of a BLDC motor (10), under high load conditions, comprising: using the unipolar pulse width modulation pattern ON_PWM to drive the BLDC motor (10); determining if there is residual current by means of monitoring the voltage of the phases that opens using a voltage observer (40); while there is residual current, applying a switching pattern, on the switches (S1-S6) of the BLDC motor (10), which superimposes the pulse width modulation pattern used and maximizes the voltage in the open phase for the accelerated extinguishing of said residual current, said switching pattern comprising: opening the switch of the phase maintained driven when changing the electrical position; and closing the switch related to the phase that was driven when changing the electric position.

Abstract: The present invention refers to a starting method with two-levels modified and discrete fixed-time or fixed-frequency hysteresis current controller, under high load conditions, of a BLDC motor (10) with trapezoidal-shaped induced voltages, wherein the BLDC motor (10) is driven by an inverter bridge (30) with only one current sensor (20) positioned in the busbar, controlled by means of a processing unit associated to an analog-digital converter, wherein the novelty basically comprises the fact that: the intensity of the BLDC motor current (Im) is controlled by means of the two-levels and discrete fixed-time or fixed-frequency hysteresis current controller.
