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 H
DCR = DCRtable × Wpri
= 0.130 × 3 = 0.39 Ohms
VT
= VTtable × Wpri
= 70.2 V-sec
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

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
