Notes:
1. These gate drive transformers are meant to operate between 50 and 300 kHz with
3
a 12V, 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 = 10 * (Drive Voltage) * (Don) / (Frequency in kHz)
B. Calculate the operating flux density (B): B
PK
(Gauss) = X * ET/Ff where:
Ff = 1 for unipolar drive applications and 2 for bipolar drive applications,
X = 40 for -NL, 33 for -ANL
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:
Copper Loss (W) = 7.5E-5 * (Frequency in kHz)
1.67
* (X * ET/1000)
2.532
X = 20 for -NL, 16 for -ANL
C. To calculate temperature rise, use the following formula:
.833
Temperature Rise (C) = 60.18 * (Core Loss(W) + Copper Loss (W))
4. 500Vrms Hi-Pot between pins 5 & 6
5. NL versions, which use triple insulated Teflon wire on the drive winding and magnetic
wire on the gate windings , are TUV certified.
ANL versions, which use triple insulated wire on both the drive and gate windings, are
compliant with IEC 61558, IEC 61010 & IEC 60601.
