HPV power inductors for 800 V DC bus, 15–30 kHz
33 standard parts for 15 A to 150 A rms – powder-core toroids with Litz winding, sized for boost and buck stages on an 800 V DC link (up to ≈ 65 kW per inductor set).
Every HPV part is dimensioned so that the ripple current stays at 40 % of Irms at D = 0.5 on an 800 V bus: 4 · ΔI · L(Ipk) · f ≥ 800 V. The inductance is held at peak current (powder-core roll-off included), so the rated power P ≈ ½ · Vbus · Irms is available at the full bus voltage.

Ratings at Ta 50 °C, still air, class F (155 °C). 60–150 A ratings are supplied as matched sets of 2, 3 or 5 identical units connected in series to keep each unit below ≈ 7 kg and Ø 146 mm. For 150 A, two interleaved HPV075 phases are often the better system choice – ask us. Mounting: aluminium L-bracket or base plate. Every part number has its own page and datasheet.
