Connecting primary windings in parallel
When primary windings (Wpri) are connected in parallel, DCR decreases,
current ratings increase, and inductance and volt-time product remain
the same.
Example: For HPH-2400L, connect two primary windings in parallel:
Inductance = Inductancetable
= 194 H
DCR = 1
÷ [Wpri × (1 ÷ DCRtable)]
= 1
÷ [(2 × (1 ÷ 0.030)] = 0.015 Ohms
VT
= VTtable
= 131.9 V-sec
Irms = Irmstable × Wpri
= 2.90 × 2 = 5.8 A
Connecting secondary windings in series
When secondary windings (Wsec) are connected in series, Irms
remains the same, but DCR increases.
Example: For HP6-2400L, connect four secondary windings in series,
creating a center tap at pins 9 and 5. For each half of the secondary:
DCR = DCRtable × Wsec
= 0.030 × 2 = 0.060 Ohms
Irms = Irmstable
= 2.9 A
Create a 100 Watt, 1 : 2, half bridge forward converter transformer with center tapped secondary
Choose HP6-2400L
Vin = 36 – 57 Vdc; Vout = 24 V, 4.2 A

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
