i am trying to make dc-dc boost converter but i dont know how to use powergui block of simscape.I have copy the error in Body which i got .one more error i got is

<http://mathworks.com/matlabcentral/images/surf.gif>00) consecutive zero crossings. Consecutive zero crossings will slow down the simulation or cause the simulation to hang. To continue the simulation, you may 1) Try using Adaptive zero-crossing detection algorithm or 2) Disable the zero crossing of the blocks shown in the following table. -------------------------------------------------------------------------------- Number of consecutive zero-crossings : 1332 Zero-crossing signal name : Sf0 Block type : S-Function Block path : 'untitled1/powergui/EquivalentModel1/State-Space' -------------------------------------------------------------------------------- -------------------------------------------------------------------------------- Number of consecutive zero-crossings : 667 Zero-crossing signal name : RelopInput Block type : RelationalOperator Block path : 'untitled1/PWM Generator/Relational Operator' -------------------------------------------------------------------------------- -------------------------------------------------------------------------------- Number of consecutive zero-crossings : 666 Zero-crossing signal name : SwitchCond Block type : Switch Block path : 'untitled1/ igbt/Model/Continuous/Switch' -------------------------------------------------------------------------------- You can turn off this message by using the MATLAB command: set_param('untitled1','MaxConsecutiveZCsMsg','none');
