ANL versions, which use PFA insulated wire on both the drive and gate windings, are 1. The max ET is calculated to limit the core loss and temperature rise at 100KHz based compliant with IEC 62368-1, IEC 61558-1, IEC 61010-1 & IEC 60601-1 for basic insulation. on a bipolar flux swing of 2200 gauss Peak. This value needs to be derated for higher frequencies using the temperature rise calculation. 5. 5mm creepage distance between ANL gate windings satisfies IEC62368-1 & IEC61558- 1/-2-16 requirement for basic insulation with working voltage up to 500Vrms, OVC II, 2. The temperature rise of the component is calculated based on the total core loss and Pollution Degree 2 and altitude up to 2000 m. There is 2.5mm creepage between gate copper loss: and drive windings. A. To calculate total copper loss (W), use the following formula: 2 Copper Loss (W) = Irms * (DCR Drive + ( of Gates) * DCR Gates) 6. Unless otherwise specified, all testing is made at 100kHz, 0.1V AC. B. To calculate total core loss (mW), use the following formula: 1.89 2.1 Core Loss (mW) = 2.64E-10 * (Frequency in kHz) * (K1 * ET) 7. Optional Tape & Reel packaging can be ordered by adding a T suffix to the part Where ET = (V * Duty Cycle) / Frequency number (i.e. PH9572.111NL becomes PH9572.111NLT). Pulse complies to industry C. To calculate temperature rise, use the following formula: standard tape and reel specification EIA481. Temperature Rise (C) = 140 * (Core Loss(W) + Copper Loss (W)) 3. Continuous isolation voltage confirmed by partial discharge measurement.
