摘　　要：论文提出了一种采用电力电子变压器,替代工频变压器的煤矿井下照明信号新型综保装置。该装置的电力电子变压器由整流环节、高频隔离环节、三相逆变环节构成。为了使其工作在较宽输入电压范围内,针对其中的高频隔离环节进行了建模,并设计了校正环节。通过理论分析和仿真表明,煤矿井下照明信号新型综保装置可以稳定的工作在较宽的输入电压范围内,适应煤矿井下各类照明负载的需求。The article proposed a design using power electronics transformer（PET） to replace traditional line transformer in illumination inte-grated protection devices.The PET involved consists of rectifier unit,high-frequency isolation unit and three-phase inverter unit.The highfrequency isolation unit introduces the three-level half bridge to make the device to support higher voltage level.The new design is more compact in size compared to the traditional one.The theoretical analyses and simulation results show that the device is capable for various il-lumination application of underground coal mine in relative wide range of operation voltage level.
