high voltage generation system
high voltage generation system
(OP)
Hi all,
hope I'm in the right forum now.
We are working on a helicopter project that needs high voltage supply of approx. 800V.
The plan is to generate standardised 270V and then convert it up. May be there are other options. The importance is that it must be compromised with low weight and volume.
Do you know potential suppliers for airborne generators and converter?

RE: high voltage generation system
What's the 800V going to be used for? Typically, load equipment is supplied with one of the standard supply voltages, 28 Vdc, 115Vac, etc. If a subsystem requires some other voltage, its best to let those engineers take responsibility for integration and certification of the supply and load together.

I'm also wondering if this is for AC or DC as well. Different options apply for either case.
Also might be best if you specify if the power is required on board, or in a towed device? Continuous or pulsed? Current?

For DC, it depends on your power requirements: ht

RE: high voltage generation system
You need a list of requirements to fill out before you can get started:
1. Certification basis for compliance purposes
2. Power characteristics:
2.1 Duty cycle,
2.2 Power requirement (watts)
2.3 Voltage input, voltage AC or DC
2.4 Voltage output, voltage AC or DC
If AC, single phase or 3 phase
3. Weight maximum
4. Volume constraints: LxWxH
5. Structural Mount requirements (locations of possible pount points). Flight and emergency alighting load factors.
6. Availability of cooling air.
7. Availability of aircraft grade electrical wiring, terminal blocks, connectors and switches CB's, fuses, etc rated to 800V.
Make sure that your interfaces with the equipment that requires the high voltage are all clearly defined so that you don't get caught out by "changes".
My experience with people who want to do this kind of thing is that they are totally focussed on their end and do not always adequately disclose the detail needed for an effective showing of regulatory compliance. Keep ahead of that facet of the exercise.

RE: high voltage generation system
Your reminders you made are clearly known to me.
Yet the actual question was not covered. Never mind, meanwhile I found a number of suppliers for Power supply components/ systems like Honeywell, Goodrich, Jenoptik and others.
