Formulas used to calculate electrical characteristics

Connecting windings in series:

Connecting windings in parallel:

Create a 1:1 gate drive transformer

Choose HP1-1400L
Part number Inductance (µH) Percent Tolerance DCR max (Ω) Volt-time product (V-µs) Irms (A)
HP1-1400L 89.6 25 0.13 23.4 0.74
Connecting primary windings in parallel:
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 = Inductance(table) × Wpri2 = 89.6 × 9 = 806.4 μH
  • DCR = DCR(table) × Wpri = 0.130 × 3 = 0.39 Ohms
  • VT = VT(table) × Wpri = 70.2 V-μsec
  • Irms = Irms(table) = 0.74 A

Connecting secondary windings in parallel:
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:
