摘要

本文采用三次谐波电流注入技术的前端变换器，使输入电流形状接近正弦。此处采用锯齿形变压器作为电流注入装置，从而有效地利用了锯齿形变压器的优点。输出级的三次谐波电流注入装置与三电平升压变换器一起增加直流链路电压，电流通过锯齿形变压器注入。采用三次谐波电流调制前端结构，可以很好地提高电能质量，适用于大电流、低电压的通信负载。对12kw负载进行了广泛的仿真，并通过实验装置验证了仿真结果。对实验装置进行了降低额定电压的测试，并给出了测试结果。

Current injection based front-end power quality improved converter for telecom load

In this paper a front-end converter having third harmonic current injection technique is used for improving input current shape as near sinusoidal. Here zig-zag transformer is used as the current injection device so that the advantages pertaining to zig-zag transformer is utilized effectively. The third harmonic current injection device along with the three-level boost converter at the output stage will increase the dc-link voltage and the current is injected through zig-zag transformer. The power quality is well improved using third harmonic current modulated front-end structure which is very well applicable to telecom load having the high current low voltage. Extensive simulation is carried out for the 12 kW load and the results are verified through experimental setup. The experimental setup is tested for reduced voltage rating and the test results are presented.
