摘　　要：级联型谐波发生器每一相由若干个背靠背功率单元级联而成，能通过较高的等效开关频率输出给定幅值的基波与2-50次谐波，有效地提高了输出电压等级与输出波形质量；可为各类高低压设备提供谐波源。测试其在谐波下的运行工况。采用数字信号处理器（DSP）＋现场可编程门阵列（FPGA）构建控制系统产生触发脉冲具有很好的实时性与可靠性，通过工业样机试验，证明了此方法的正确性。The cascade harmonic generator each phase consists of several back to back power cells, which can output given amplitude fundamental wave and 2-50 harmonics through high equivalent switching frequency, and effectively increases the output voltage level and the quality of output waveform.h can be used as harmonic source for all types of high and tow voltage equipments, testing their operating conditions under harmonics.The control system constructed by digital signal processer（DSP）＋field programmable gate array （FPGA） to generate trigger pulses has good real-time characteristic and reliability.The correctness of the method is proved.
