#91020 - ok than Responding to: ???'s previous message |
i think most of users are suggesting me chip from (cygnal)silab
i also considering my self as one of them i am going to use c8051f020 from silab for better resolution and speed it will also solve my problem of more i/o's and adc which i am using off chip right now and lathces to increse i/o's,there is no other solution. as erik says "I do not think that there will be a noticeable/measurable difference between induction heating at 20.001 and 20.002 Hz. " agreed with erik there is no noticeable difference up to 25hz step but at step greater than 25hz a noticeable change is there in inductance of transformer and it heavily load the line uneven bumps rather than smooth control and system destablise. with silabs i can get 40ns resolution and step vary from 32 to 128 hz as i increase frequency from 20khz to 40khz still worse to accept. kuldeep singh |
