## **Notes:**
1. The ET Max is calculated to limit the core loss and temperature rise at 1MHz based on a bipolar flux swing of 61mT Peak.
2. For Push-Pull topology, where the voltage is applied across half the primary winding turns, the ET needs to be derated by 50% for the same flux swing.
3. The applied ET may need to be further derated for higher frequencies based on the temperature rise which results from the core and copper losses
- A. To calculate total copper loss (W), use the following formula:
- Copper Loss (W) = Irms_Primary[2] * DCR_Primary + Irms_Secondary[2] *DCR_Secondary
- B. To calculate total core loss (W), use the following formula:
Core Loss (W) = 5.42E-11 * (Frequency in kHz)[2.0325] * (61 * [ET/ET Max])[2.018]
- Where ET is the applied Volt Second, ET Max is the rated Volt Second for 140mT flex swing C. To calculate temperature rise, use the following formula: Temperature Rise (°C) = 140 * (Core Loss(W) + Copper Loss (W))
4. Creepage and clearance is in accordance with IEC 61558-1 for reinforced insulation to a working voltage of 400Vrms (for basic insulation to a working voltage of 800Vrms) based on material group III, pollution degree 2, OVC II and 5000m altitude.
5. Rated voltage is based on a positive partial discharge test (discharge < 10pC) for the profile shown in page 3, in accordance with IEC60664 for basic insulation. In an application which requires a reinforced insulation barrier, a rated voltage of the equivalent peak working voltage, 880Vpk, is defined and confirmed by partial discharge testing.
