Hi. In Simulink modeling, what can we do to ensure that the switching waveforms of the duty cycle and 1-duty cycle are not in phase?

q1 is the duty cycle (D), and q3 is the 1-duty cycle (1-D)

[Danikha Shyken]

this is the simulink model

[Danikha Shyken]

D= 47.37% or 0.4737

If you want both to be in 90 deg out of phase with each other , you can simply use the not, the easiest method. Ofcourse assuming the signal is a boolean signal.

[Danikha Shyken]

where do i put the "not" sir? and the signal data type is double

[madhan ravi]

like you did in your other recent question, considering my sugeestion there

[Danikha Shyken]

AAAH I see, okay, sir. Thank youu

Connect q1 to NOT gate and use Data Type Conversion block if error message occurs.Output of NOT gate is q3. Alternatively connect q1 to MATLAB User Defind Function or Fcn block with value (1 - u(1)). Output of Fcn block is q3.
