Notes:
- The max ET is calculated to limit core loss and temperature rise at 100KHz based on a bipolar flux swing of 2100Ga Peak. This value needs to be derated for higher frequencies using the temperature rise calculation.
- Temperature rise calculation: Temperature Rise (°C) = 71 * (Core Loss(W) + Copper Loss (W)).
- Copper Loss (W) = Irms * (DCR_Drive + (# of Gates) * DCR_Gates).
- Core Loss (W) = 5.1E-10 * (Frequency in kHz) * (K1 * ET).
- Continuous isolation voltage confirmed by 125°C/1000hrs accelerated aging with bias voltage applied between gate and drive windings.
- All testing is made at 100kHz, 0.1VAC unless otherwise specified.
