Expert Strategies: Tips & Tricks
Pro-Tip: The 'Duty Cycle' Shortcut
For a Buck converter, $V_o = D V_{in}$. For a Boost converter, $V_o = V_{in}/(1-D)$. Remembering these simple transfer functions allows you to solve 30% of PE questions in seconds.
Logic: Inductor Current
Remember that inductor current cannot change instantaneously. In converter problems, always look for the "steady-state" behavior where the net energy change in the inductor over one cycle is zero.
