D-CLASS AMPLIFIER (PULSE WIDTH MODULATION-PWM)

|Hi,
I am just new to simulink. I want to construct the model of a d-class amplifier for audio applications. I need a specific block that can take as input a sinusoidal signal, then compare it with a trianlge signal (as this seems to be a really common method) and then produce a PWM pulse, at the output. Later on, I intend to connect this output to a POWER MOSFET bridge, which works as a really fast switch, in order to get an amplified signal.
Is there any block inside the simulink library that can produce PWM pulses from a sinusoid or even a random audio signal? Has anyone tried something relative to this kind of conversion?
Thank you, forr any ideas or help
Andreas
