讨论了一种用于大功率多电平变换器的具有高绝缘性能的主动冷却大功率高频变压器。该变压器设计功率为350kw，采用非晶铁芯材料和同轴绕组实现。特别要注意的是绝缘问题，因为必须更详细地研究介电损耗和边缘非常陡峭的电压波形的影响，以保证器件的长寿命。
An actively cooled high power, high frequency transformer with high insulation capability for use in a high power multilevel converter is discussed. The transformer is designed for a power level of 350 kW and is realized with amorphous core material and coaxial windings. Special attention is paid to the insulation problem, since the dielectric losses and the influence of the voltage waveform with very steep edges have to be investigated more in detail to guarantee a long lifetime of the device.
