In Figure 7, when the duty cycle is equal to 100%, D
equals 1. When we set D equal to 1 in equation (3), notice
(3) becomes the same as equation (2), if we assume V
equals BRT. Using a 100% duty cycle is the same as
applying a constant DC voltage to the BRT pin. In this
instance, Figure 7 is exactly the same as Figure 1.
