| Apr 24 at 19:26 | comment | added | Bart Simons | Hi, unfortunately it is not a steady state problem. I'm interested in solving the problem in the time domain, as a transient simulation. So therefore I need to get the first order differential equations. All equations are kind of easy to write doen except for C2, C3 and C4. I don't see how to express e.g for C2 the current IC3 in terms of the input variable of the state space model. That is the main reason to ask the question here. Maybe another place is better to ask this mathematical question. | |

If it's steady-state, it might be better to represent everything in terms of impedances -- for example, R1 and L1 form a high-pass filter, as do R2 and L2. Then L3 and C3 form a "tank", as well as L4 and C4. Then you can plot the frequency response -- from your simulation, you get peak gain at 100 kHz. | |

| Apr 24 at 12:57 | comment | added | Bart Simons | Hi, I know, that does not matter. You can specify starting conditions for all the components. Capacitor C1 will be charged at t=0. | |
