[H-GEN] Inverters and Computers

[Frank Brand]

Anyone have any opinions,

A friend of mine wants to use his desktop computer in a mobile
situation. He wants to obtain 240 V AC from an inverter.

He has three option viz,

1. Sine Wave form (expensivest solution).

2. Simulated sine wave ie. cropped sqare wave form (mid-cost solution).

3. Square wave form (cheapest solution).

My question is - Can he save some money and obtain the sqare or
simulated wave form inverters. Taking into account that the power so
generated then goes through a transformer will the voltage cleanliness
(? what the fsck do you think I mean by this) and voltage stability be
sufficient for the computer to run OK?

Any ideas?

Seems an expensive way of going from 12V DC to 240 V AC to 5 V DC again
doesn't it?

TIA.
