An active power factor correction (APFC) front-end converter was developed for a field-orientation-controlled (FOC) permanent magnet synchronous motor (PMSM) drive. The decoupled FOC PMSM drive was designed on the basis of the stator current and flux to achieve the maximum torque-to-current ratio. Linear control was implemented for two-axis stator current controllers and a speed controller, with the stator current measured using Hall effect current sensors. The proposed bidirectional power flow front-end converter enables the FOC PMSM drive to maintain unity power factor operation in both motoring and regenerative braking modes, thereby enhancing power factor performance and promoting energy efficiency. The system was simulated using MATLAB/Simulink®, and all control algorithms were implemented on a Renesas RX62T microcontroller to generate pulse width modulation (PWM) signals for driving the APFC front-end converter and the PMSM. Both simulation and experimental results validated the effectiveness of the proposed method.
