In this study, a current source PWM rectifier (CS-PWM) system combined with vector-oriented control method has been developed for a three-phase self-excited induction generator (SEIG) supplying isolated DC load. Unlike the conventional rectifier scheme, the proposed CS-PWM rectifier uses two numbers of active switches in each leg that are connected with power diode in series to prevent the current reversal of DC link. The adopted decoupled control strategy maintains a constant DC load voltage of 220 V and CS-PWM rectifier input current harmonic content of only 4.82% at the rated 50 Hz frequency. The proposed system performance has been predetermined for various operating conditions using binary search algorithm (BSA) technique and the analysis has been carried out. An abc-dq modeling has been employed for the dynamic performance analysis of the induction generator and simulation of the proposed system has been carried out under both steady state and transient state using Matlab/Simulink toolbox to validate the successful working under various operating conditions.

在这项研究中，开发了一种电流矢量PWM整流器（CS-PWM）系统，该系统结合了矢量控制方法，用于提供隔离直流负载的三相自励感应发电机（SEIG）。与常规整流器方案不同，建议的CS-PWM整流器在每个支路中使用两个有源开关，这些开关与功率二极管串联，以防止DC链路的电流反向。所采用的去耦控制策略可保持220 V的恒定DC负载电压，并且在额定50 Hz频率下，CS-PWM整流器的输入电流谐波含量仅为4.82％。使用二进制搜索算法（BSA）技术已针对各种运行条件预先确定了建议的系统性能，并进行了分析。一个ABC-DQ 建模已用于感应发电机的动态性能分析，并使用Matlab / Simulink工具箱在稳态和瞬态下对所提出的系统进行了仿真，以验证在各种工况下的成功工作。
