Abstract
This proposed work investigates the performance of dc voltage of a three-phase Active Front-End (AFE) Sinusoidal Pulse Width Modulated (SPWM) rectifier during load switching. To obtain desired performances, a transfer function is derived in synchronous reference frame (dq), from which the gain of the PI controllers are estimated and observed the performance accordingly. In this research, the load current is feed-forwarded with d-axis current by a suitable choice of gain factor, which results a fractional feedback d-axis current control and improves the transient behaviour simultaneously. This will unalter the other performance parameters of the system such as, UPF operation, less Total Harmonic Distortion (THD) of input current, dc voltage boost etc. All the simulation results exhibits satisfactory performance and validated with a prototype developed using STM32F303RE microcontroller accordingly.
本论文研究了三相有源前端（AFE）正弦脉宽调制（SPWM）整流器在负载切换时的直流电压性能。为了获得理想的性能，在同步参考帧（dq）中导出了传递函数，并由此估算出 PI 控制器的增益，从而观察其性能。在这项研究中，通过适当选择增益系数，负载电流与 d 轴电流前馈，从而实现了分数反馈 d 轴电流控制，并同时改善了瞬态性能。这将不会改变系统的其他性能参数，如 UPF 运行、较低的输入电流总谐波失真 (THD)、直流电压提升等。所有仿真结果均显示出令人满意的性能，并通过使用 STM32F303RE 微控制器开发的原型进行了相应验证。
