LCL Transmitter - DC Offset

0 votes
Hi All,

I am currently designing a LCL network on the transmitter side of coupled coils. The waveform shapes are what I expect for such a system, however I am seeing DC offset in the current waveforms in both inductors where I would not expect any. I have tried with a voltage controlled source and H-Bridge, In addition to simulating the entire circuit to no avail. I am wondering if I have some parameter in PLECS set up incorrectly?

From a quick look, the model has no (resistive) damping. Perhaps you could add a source impedance, e.g., 1mOhm in series with the voltage sources to get the desired effect?
