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 sales@convernova.com.

Send us your specifications and get a quote

Free 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.

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

Magnetic design Manufacturing Something else

Waveforms and files

Attach waveforms and specification 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

Anything else we should know

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.

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
