I want to supply a gate pulse to an IGBT switch in DC-DC converter with a duty ratio of 40% from 0 to 2 seconds and 2 to 4 seconds with simulation time of 6 seconds and i want to disconnect the gate pulse to switch from 4 to 6 seconds. how to do this in simulink. The switching frequency of IGBT switch is 20 kHZ.

@Manikanta Aditya, which Pulse Generator block are you referring to? I didn't find the place to "Define Variable Duty Ratio in Pulse Type Attributes".

I meant the Pulse Generator block in Simulink that allows defining a variable duty ratio based on time.

I assume this is in Simulink. You can use an AND logic block or Product block to multiply two signals. One is the regular 40% duty cycle PWM all the time, the other is this On/Off signal based on pre-determined timing or based on event by other Simulink signal.

You could use a Signal Builder block. Or use a Switch block, before t<4, pass the PWM. After that, switch to 0.
