本文讨论了拟安装在6.6 kV工业和公用事业配电系统上的无变压器STATCOM（静态同步补偿器）的潜力。STATCOM由一个额定值为1 MVA的五电平二极管箝位PWM转换器和一个额定值为6 kVA的电压平衡电路组成。此外，本文设计，构建，并测试了一个200-V的10-kVA的STATCOM的基础上，一个五电平转换器的载波频率为3 kHz和一个电压平衡电路的开关频率为3 kHz。STATCOM及其实验波形验证了6.6 kV无变压器STATCOM的可行性和有效性。
This paper discusses a potential of a transformerless STATCOM (static synchronous compensator) intended for installation on the 6.6-kV industrial and utility distribution systems. The STATCOM consists of a five-level diode-clamped PWM converter rated at 1 MVA, and a voltage-balancing circuit rated at 6 kVA. Moreover, this paper designs, constructs, and tests a 200-V 10-kVA STATCOM based on a five-level converter with a carrier frequency of 3 kHz and a voltage-balancing circuit with a switching frequency of 3 kHz. The STATCOM and its experimental waveforms verify the viability and effectiveness of the 6.6-kV transformerless STATCOM.
