摘　　要：针对目前基于可控硅的核电站棒控系统存在输出电流纹波大、电流上升和下降时间长等特点,提出了基于绝缘栅双模型晶体管(IGBT)的捧控系统。IGBT作为新型大功率开关器件,具有电压型控制、输入阻抗大、驱动功率小、控制电路简单、开关损耗小、工作频率高和元件容量大等优点。实际应用表明,IGBT减小了棒控系统输出的电流纹波和电流上升、下降时间,十分适合应用于核电站棒控系统中。At present , most of the rod control system in nuclear power stations are using SCR, so the ripple of output current is big, and the rising time and calling time of the current are long, to overcome this demerits, the rod control system based on IGBT is proposed. IGBT is a new type of large power switching device; it features voltage control, high input impedance, small driving power, simple control circuit, low switching loss, high working frequency and large capacity. Practical application shows that the ripple and current rising and falling time are decreased, this shows that IGBT is suitable for application of rod control system in nuclear power station.
