my stb controller crad

sahu · Feb 27, 2012

here the function detels of my stabilizer controller card .

Only one L.T. is required. its wiring as per my diagram.
******************************************************
* ITS stb wiring diaGRaM for 90 Volt to 290 Volt *
******************************************************

************************************************************************************************
1- When we connect 95V input from variac the output should be 200V on output relay-4 on com point(POLE) .Now increase input and check output.When output reaches between 240 - 245V ,we move preset wiper till
relay-3 goes ON and
relay-1 ,relay-2 are off

output will reach near about to 205V.now input near about 115volt.
THIS STEP WE CAN SAY STEP_0 .
************************************************************************************************

2- now input near about 115volt.Agen increase input and check output.When output reaches between 240 - 245V.now input near about 137volt.
relay-1 goes ON and now
relay-3 goes off .
relay-2 are off

output will reach near about to 205V.now input near about 167volt.
THIS STEP WE CAN SAY STEP_1 .
************************************************************************************************

3- now input near about 167volt. Agen increase input and check output.When output reaches between 240 - 245V.now input near about 200volt.
relay-1 all redy on in STEP_1 .
relay-3 goes on .
relay-2 are off

output will reach near about to 205V.now input near about 200volt.
THIS STEP WE CAN SAY STEP_2 .
************************************************************************************************

4- now input near about 200volt. Agen increase input and check output.When output reaches between 240 - 245V.now input near about 240volt.
relay-1 all redy on in STEP_1 & STEP_2.
relay-2 goes on and now
relay-3 goes off .&

output will reach near about to 205V.now input near about 240volt.
THIS STEP WE CAN SAY STEP_3 .
*************************************************************************************************

5- now input near about 240volt. Agen increase input and check output.When output reaches between 240 - 245V.
relay-1 all redy on in STEP_1 , STEP_2 & STEP_3 And also
relay-2 all redy on in STEP_3 .. & now
relay-3 goes on .&

output will reach near about to 205V.now input near about 240volt.
THIS STEP WE CAN SAY STEP_4 .

but it is not work as i want .pl guide me where i wrong ??

Any body guide me.

Hi Sahu.... I'm not entirely happy with your switch statement... The 'break;' statements are in 'if' loops... So if none of the if statemets are true... the next 'case' will be executed.

Code:

switch (x)
   {
   case 1:
      if(a)
         {
          arguments;
         }
       if(b)
         {
          arguments;
         }
       if(c)
         {
          arguments;
         }
      break; ----------> break goes here.
   case 1:
        .................rest...
  }

In your powerlevel functions.. There is no need for the break statements

thank u Mr .Ian Rogers
now i remove break statements in my powerlevel functions..
so now code are as ....

Code:

 switch (step_mode.rem)
          { 
           case 0:
      if ((ch >= 10) && (ch <= 130)) 
          {G=1;
          power_level_1();
            //break;
           }
          if ((ch >= 137) && (ch <= 167))  
          {B=1;
          power_level_2();//RL3=ON
           a=a+1;     //step_mode = step_mode+1;  // goto step 2
           // break;
          }
                       break;
     case 1:
     if (ch < 115) 
          {B=1;G=1;
          a=a-1;  // step_mode = step_mode - 1;  // Callback to step 1 (last step)
              //  break;
          }
        if ((ch >= 119) && (ch <= 140)) //RL1=ON &  //RL3=OFF  now  case 2
          {C=1;
          power_level_3();
               // break;
           }
        if ((ch >= 144) && (ch <= 177)) //RL1=ON &  RL3=ON
          {D=1;
          power_level_4();
              a=a+1;  // move to next step
              // break;
          }
                 break;

case 0 work very well . but problem is here

if ((ch >= 137) && (ch <= 167))
{B=1;
power_level_2();//RL3=ON
a=a+1; //step_mode = step_mode+1; // goto step 2
// break;
}
break;
case 1:
if (ch < 115)
{B=1;G=1;
a=a-1; // step_mode = step_mode - 1; // Callback to step 1 (last step)
// break;
}
if ((ch >= 119) && (ch <= 140)) //RL1=ON & //RL3=OFF now case 2 not work
{C=1;
power_level_3();
// break;
}

Maybe its not a switch statement you need.... If case0: is executed then case1: will not be executed in the same cycle... That's the nature of this control structure.

sahu · Mar 3, 2012

so how do it ?

Ian Rogers · Mar 3, 2012

Its very difficult for me to comment as I don't see what your trying to achieve.... The last time we did this I could only offer examples... same again here.

sahu · Mar 3, 2012

it mens i post here complete code or mail u .

Ian Rogers · Mar 3, 2012

No you don't need to do that... I'll take the todo list from your original post. Then I'll code a resolve (I use hi-tech, I don't have ccs, you can convert as necessary ) .

It'll take a day or so...

sahu · Mar 3, 2012

thank u very much for Ur cooperation

Ian Rogers · Mar 4, 2012

May I see the div_t structure?

Also... I have tried and tried, but I cant work out the logic... How do you change the step_mode? The input voltage is monitored! but how the outputs are worked out.

For instance... Relay 1, when activated, applies the input voltage onto the 290v rail ??? OR relay 2 redirects the input voltage to the 200v or 137v rail

I take it that the 22v output should be stable with the voltage at any of the four inputs 6/9/11 & 13 : 1 ratio? What is the point of the output?
