Development of Speed Control System for BLDC Motor with Power Factor Correction

The paper considers the issue of developing a system for controlling the speed of the BLDC motor when the load torque changes. This control system is built up as the field-oriented control (FOC) algorithm under the assumption of sinusoidal input voltages, which allows to exclude switching sections for the characteristic and periodic change in the structure of the mathematical model of the motor. To get the power of the BLDC motor, we using a power supply unit with a power factor corrector (PFC). PFC not only be able to maximize power from the electricity, but also be able to eliminate short pulses of the mains current.
