NOTES:
1. These gate drive transformers are meant to operate between 50 and 300 kHz with 3. The temperature rise of the component is calculated based on the total core loss
and copper loss:
a 12 V, 45% bipolar waveform.
A. To calculate total copper loss (W), use the following formula:
2. The peak flux density should remain below 2100 Gauss to ensure that the core
Copper Loss (W) = Irms
2
* (DCR_Drive + (# of Gates) * DCR_Gates)
does not saturate. Use the following procedure to calculate the peak flux density:
B. To calculate total core loss (W), use the following formula:
A. Calculate the Volt-碌sec product (ET): ET = (Drive Voltage) * (Don) /
Core Loss (W) = 7.5E-5 * (Frequency in kHz)

C. To calculate temperature rise, use the following formula:
B. Calculate the operating flux density (B): Bpk (Gauss) = 40.32 * ET/Ff where:
Temperature Rise (C) = 60.18 * (Core Loss(W) + Copper Loss (W))
