DRIVE
1. These gate drive transformers are meant to operate between 50 and 300 kHz with
a 12 V, 45% bipolar waveform.
2. The peak flux density should remain below 2100 Gauss to ensure that the core
does not saturate. Use the following procedure to calculate the peak flux density:
A. Calculate the Volt-μsec product (ET): ET = (Drive Voltage) * (Don) /
(Frequency in kHz) * 10
3
B. Calculate the operating flux density (B): Bpk (Gauss) = 40.32 * ET/Ff where:
Ff = 1 for unipolar drive applications and 2 for bipolar drive applications
3. The temperature rise of the component is calculated based on the total core loss
and copper loss:
A. To calculate total copper loss (W), use the following formula:
Copper Loss (W) = Irms
2
* (DCR_Drive + (# of Gates) * DCR_Gates)
B. To calculate total core loss (W), use the following formula:
Core Loss (W) = 7.5E-5 * (Frequency in kHz)
1.67
* (20.16 * ET/1000)
2.532
C. To calculate temperature rise, use the following formula:
Temperature Rise (C) = 60.18 * (Core Loss(W) + Copper Loss (W))
