What will be the voltages across capacitor C1 and inductor L1 in terms of Vg,D,R? From the amp charge balance equation, i1=-io *D because i2=io.From my observation, Vc1= Vg for 0<T<DTs and Vc1= Vg-vL1 for DTs<T<Ts. But I can't reach the equation of VL1 and Vc1 using Vg,D,R. Please help me to express the equations.
