Consider an ideal Buck converter with the added output capacitor.
a) Derive the circuit differential equations, in terms of d(iL))/dt and d(vC))/dt.
b) Convert part a) into the state-space eq...
a) d(iL))/dt = (Vin) - Vout))/L, d(vC))/dt = -iL)/C
b) d(iL))/dt = (Vout) - Vin))/L, d(vC))/dt = iL)/C
c) d(iL))/dt = (Vin) - Vout))/C, d(vC))/dt = -iL)/L
d) d(iL))/dt = (Vout) - Vin))/C, d(vC))/dt = iL)/L
