single-stage single-phase dc-ac converter

hi sir, im modeling a fuel cell grid connected with a single-stage single-phase dc-ac converter(Differential inverter), this converter is made of two dc-dc converter in which the igbts gate singnals are pwm and i dont know how to apply signal to gate in order to have sinusoidal output, and send me the pwm generator block if its possible

SimPowerSystems alreadhas a PWM Generator block in the Control and Measurement library.

You can either feed it a sinusoidal wave as an input (duty) or generate the sinusoid internally in the block.

As you can see in the bottom of that page above, there is an example model "power_PWMGenerator2Level" you can also take a look at for help.
