A Review of Insulation Stress and Partial Dischargein Medium-Frequency Transformers Under Fast Repetitive Voltage Pulses

The use of wide-bandgap power devices in solid-state transformers enables higher switching frequencies and power densities, but it also exposes medium-frequency transformer insulation to fast repetitive voltage pulses. Short rise times, high dv/dt, high repetition frequencies, and harmonic content can produce nonunifor...
