B. Practical Issues for L and C
2. DC Current Operating Point in a Buck-boost circuit via Capacitor charge balance We will show below by separate calculation that I L = I o + I in. I C-V o /R DT s D'T s t i C + i R = 0-I L - V o /R i C + i L + i R = 0 We find that the inductor current is: I V L RD ≡ − o ' and / or I V D D R L ≡ g ( ')2 Example: V o = -20V, V g = 30V and ...
