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) = Irms2 * (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-µsec product (ET): ET = (Drive Voltage) * (Don) / Core Loss (W) = 7.5E-5 * (Frequency in kHz)1.67 * (20.16 * ET/1000)2.532 (Frequency in kHz) * 103 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)).833 Ff = 1 for unipolar drive applications and 2 for bipolar drive applications Mechanical .810 MAX 20,57 Schematics P0584 .480 MAX 12,19 P0585 2 GATE 3 1 .750 MAX 19,05 4 8 DRIVE 10 P058X 3 9 GATE GATE Date Code Country of Origin 7 GATE 1 8 4 DRIVE 10 GATE 5 7 GATE 6 .130 3,30 1 P0584 (6 pins) 4 10 10 7 .350 8,89 1 .700 17,78 P0585 (10 pins) 7 .350 8,89 (6X) .040 .200 5,08 10 4 1 .700 17,78 .400 10,16 7 .100 2,54 (10X) .040 .200 5,08 .100 2,54 4 Weight . . . . . . . . . . . . . . . .5 grams Tray . . . . . . . . . . . . . . . . . . .20/tray Dimensions: Inches mm Unless otherwise specified, all tolerances are ± .010 0,25 US 858 674 8100 • UK 44 1483 401 700 • France 33 3 84 35 04 04 • Singapore 65 287 8998 • Taiwan 886 2 2698 0228 • Hong Kong 852 2788 6588 • http://www.pulseeng.com PC500.B (5/02) 52
