Hexa-Path Magnetics Document 613-10 Document 613-10 Revised 08/20/15 Connecting primary windings in series When primary windings (Wpri) are connected in series, inductance and volt-time product increase, energy storage and Irms remain the same, but DCR increases. Example: For HPH1-1400L, connect three primary windings in series: Inductance = Inductancetable × Wpri2 = 89.6 × 32 = 806.4 µH DCR = DCRtable × Wpri = 0.130 × 3 = 0.39 Ohms VT = VTtable × Wpri = 70.2 V-µsec Irms = Irmstable = 0.74 Connecting secondary windings in series When secondary windings (Wsec) are connected in series, Irms remains the same, but DCR increases. Example: For HP1-1400L, connect three secondary windings in series: DCR = DCRtable × Wsec = 0.130 × 3 = 0.39 Ohms Irms = Irmstable = 0.74 Create a 1 : 1 gate drive transformer Choose HP1-1400L DCR Volt-time Peak energy Part Inductance max product storage Isat Irms number (µH) (Ohms) (V-µsec) (µJ) (A) (A) HP1-1400L 89.6 ±25% 0.130 23.4 N/A N/A 0.74 Formulas used to calculate electrical characteristics Connecting windings in series Inductance = Inductancetable × (number of windings)2 DCR = DCRtable × number of windings Isat = (Isattable × 6) ÷ number of windings connected in series Irms = Irmstable Connecting windings in parallel Inductance = Inductancetable DCR = 1 ÷ [number of windings × (1 ÷ DCRtable)] Isat = (Isattable × 6) ÷ number of windings connected in series Irms = Irmstable × number of windings 1 4 Pri Sec 5 6 3 2 11 10 12 9 8 7 Primary: L= 806.4 µH DCR= 0.39 rms= 0.74 A VT = 70.2 V-µsec I Secondary: DCR= 0.39 rms= 0.74 A I |
