摘      要：Innovative test methods are required to keep up with the increased demand for insulation materials which can withstand the high-frequency square-wave voltages generated by power-electronic *** systems using high-voltage,high-frequency transformers have proven versatile and easy to *** authors investigate the application of amorphous cut cores in such *** and numerical models for the transformer and its frequency response are developed,aiding the design *** amorphous core-based transformer is designed for 8 kVpk output at 100 kHz and compared to two previous designs based on ferrite *** frequency and pulse response,as well as the high-voltage and thermal performance,are *** comparison shows that while the low parasitics of the amorphous-based transformer allow for superior frequency response,they are unsuitable for long-duration tests with high pulse repetition frequencies(25-100 kHz)due to increased core *** partial discharge inception and flashover voltage are comparable to the ferrite-based transformers.
