Difficulties in high frequency transformer modeling

Electric Power Systems Research, 2016
Traditional transformer models available in EMTP-like software packages are not capable of representing transformer behavior during a transient state, which includes high frequencies, since they usually do not adequately take into account the transformer resonant behavior caused by its highly complicated design.

High-Frequency Transformer Design With Medium-Voltage Insulation for Resonant Converter in Solid-State Transformer

IEEE transactions on power electronics, 2023
A solid-state transformer can directly convert medium voltage to low voltage (e.g., 400 V) with minimized power-conversion stages. The transformer in the dc–dc module not only provides medium-voltage insulation but also significantly affects the power ...

Multiphysics Digital Model of the High Frequency Transformer for Power Electronics Application Considering Electro-Thermal Interactions

IEEE transactions on power electronics, 2023
The high frequency transformer (HFT) applied in the power electronics operate under the combined stresses of high-frequency pulsewidth modulation (PWM) voltage and high temperature. The electro-thermal coupling effect can accelerate the aging process and

Characterization of Partial Discharges in High-Frequency Transformer Under PWM Pulses

IEEE transactions on power electronics, 2022
Partial discharge (PD) is a phenomenon often occurring in insulation system defects (cavities), which can significantly affect life and reliability. While broad knowledge on PD phenomenology of high-frequency transformers (HFT) has been achieved under ac
