Send us your specifications and get a quote

Engineering review. We aim to have a first design proposal with you within 24 hours, with the loss distribution and the parameter values, not just a price. Send what you have: if the magnetics specification is not written yet, the schematic and a waveform are enough.

01

Topology

Which topology are you converting with

Pick the topology you are converting with and the sheet keeps only the parameters it actually needs.

The schematic of whichever topology you pick appears here, and stays in view while you fill in the numbers.

What you need from us

Waveforms and files

CSV, PDF, spreadsheets, drawings and images, up to 10 MB in total. A scope capture says more than three boxes.

What does not fit in a box

02

Operating point

Complete 0% Pick a topology and this fills in with the parameters that topology needs. No filling in twelve boxes when eight of them do not apply.
03

Who you are

What to include

The more of this you send, the more of the design we can do before we come back to you.

None of it is compulsory, and the form above does not ask for most of it. This is the list we work from, in case you would rather send a document than fill in boxes.

Electrical

  • Voltages and range, e.g. 400V DC +/- 20%
  • Output and tolerance, e.g. 48V +/- 2%
  • Power and current, e.g. 10kW, 250A
  • Frequency, e.g. 100 kHz
  • Isolation, e.g. 3kV RMS
  • Efficiency target
  • Leakage and capacitance, if critical

Mechanical

  • Max dimensions, L by W by H
  • Mounting: PCB, SMD/THD, chassis, coldplate, heatsink.
  • Weight restrictions
  • Terminations and connectors
  • Orientation
  • Keepout zones and clearances
  • Pinout diagram or schematic

Environmental

  • Temperature range
  • Humidity and altitude
  • Vibration and shock
  • Cooling: natural, forced, liquid
  • IP rating and enclosure

Compliance

  • Industry standards: AEC, MIL, EN
  • Certification: UL, IEC
  • Expected production volume
  • Project timeline and urgency
  • Target price, if applicable
  • Legacy part number, for replacements

Straight answers

Sending a specification, the usual questions.

How much does the engineering review cost?
Nothing. ConverNova returns a first design proposal with estimated core and winding losses, leakage and magnetizing inductance, dimensions and expected hotspot temperature, usually within 24 hours, before the customer commits to anything.
What if I do not have a magnetics specification yet?
A schematic and a waveform are enough. Defining the magnetics specification is the part ConverNova does for the customer.
What files can I attach?
CSV waveforms, PDFs, spreadsheets, drawings and images, up to 10 MB in total. Larger files can be sent to [email protected].
