Hey guys

I'm reading an article that I'm sending attached and I have one doubt. In eq. (17) it is pointed out that
$i_{ca1}=(T_{a2}-T_{a1})I_{as}$
and in eq. (18) it is said that using a moving average technique eq. (17) can be written as
$I_{ca1}=(d_{T_{a2}}-d_{T_{a1}})I_{as}$
I didn't understand this moving average technique and why it can be written this way using the modulating waveform of each switch.

Can you explain?
