Yes, for us in Europe or in the U.S.A., but not for someone in India or Pakistan. why do you profess to know that inverters are more costly and parts are not? He is talking about labour costs + consultancy etc. Erik Malund said:

Of course, I know, that fabricating an inverter is really hard stuff. But why assuming that they cannot solve all these problems? hwre have I, by stressing that "fabricating an inverter is really hard stuff" in any way been "assuming that they cannot solve all these problems". There are, you know as well as me, some that always think "I can make it cheaper" and e.g. come out with a microvolt analog two sided board and post "why is it not steady?". Warning against the pitfalls does NOT imply an assumption. Erik Oh really, there is a difference between constructive criticism and destructive criticism , and you simply do the later one. Had you been sincere enough in your discussions you would definitely have made all your comments ATTITUDE free. Erik Malund said:
OP said: want to use microcontroller for this purpose... and the professionals use a DSP this is one more of these foolish "I can make that cheaper" ideas. You can get an inverter for a couple of hundereds (dollars), just look at the one off price of 1600V IGBTs. Erik OP asks suggest me with an MCU or a particular way, and you go your own way . I am sorry if you cannot design RF layouts its not my problem, but if someone else wants to give it a try,they are free. But you simply NAG because it is someone named ERIK who couldnt do that earlier ,therefore anyone shouldnt attempt it. I have even seen you discouraging people who tries to make switchers/DC-DC etc , what for you do that ? ,just because it is difficult for YOU? . Very clearly judged by Kai , it does reminds me too of sales people who do such activities . If you are really in design business just leave it atonce and go in for Sales you will come out with flying colors. -AP |
