Hi all,
I am writing this in the hope of getting some advice on the choice of
power devices for an electronic load I am going to build for testing a
48V DC power supply
The basic specs for the load are as follows:
Input Voltage :3 to 100 VDC
Max Current :120Amps
Max Overall Power Limited To:3500W
For the power stage, I am thinking of building 7 modules of 500W each
and paralleling them, for ease of construction and maintenance. Mostly
it is to get the heatsinks into manageable sizes.
Not having done such high powers before, I would appreciate advice on
1.What type of devices to employ (IGBTs or MOSFETs) and what
particular part numbers are readily available.
2. Where to get appropriate heatsinks.
3. Any other practical aspects which are not readily obvious when
building such equipment.
Thanks
Manvinder
