This paper presents a Direct Current Control (DCC) method designed to maintain unity input power factor, using a vector-controlled Permanent Magnet Synchronous Motor (PMSM) as the load. A three-phase rectifier with a Proportional-Integral (PI) controller is employed at the input side, and the PMSM drive is operated through an inverter controlled by Space Vector Pulse Width Modulation (SVPWM) with an additional PI controller. The proposed method consists of two stages: first, by varying the rectifier load, the system’s ability to maintain unity power factor and stabilize the rectifier DC output voltage is evaluated. In the second stage, the DC voltage is converted into AC using the SV PWM-based inverter to power the PMSM. The performance of the PMSM drive is analyzed under different test conditions, including constant and variable loads, to observe input power factor variations. The detailed parameter design of the rectifier, DCC controller, and SV PWM-based inverter is modeled in SIMULINK/MATLAB, and a hardware-in-the-loop setup is tested on a prototype. Experimental results from Hardware, both transient and steady-state conditions demonstrate the effectiveness and excellent performance of the proposed method.

摘要

This paper presents a Direct Current Control (DCC) method designed to maintain unity input power factor, using a vector-controlled Permanent Magnet Synchronous Motor (PMSM) as the load. A three-phase rectifier with a Proportional-Integral (PI) controller is employed at the input side, and the PMSM drive is operated through an inverter controlled by Space Vector Pulse Width Modulation (SVPWM) with an additional PI controller. The proposed method consists of two stages: first, by varying the rectifier load, the system’s ability to maintain unity power factor and stabilize the rectifier DC output voltage is evaluated. In the second stage, the DC voltage is converted into AC using the SV PWM-based inverter to power the PMSM. The performance of the PMSM drive is analyzed under different test conditions, including constant and variable loads, to observe input power factor variations. The detailed parameter design of the rectifier, DCC controller, and SV PWM-based inverter is modeled in SIMULINK/MATLAB, and a hardware-in-the-loop setup is tested on a prototype. Experimental results from Hardware, both transient and steady-state conditions demonstrate the effectiveness and excellent performance of the proposed method.
