On Energy Conversion in Port-Hamiltonian Systems
Arjan Van der Schaft, Dimitri Jeltsema
We study port-Hamiltonian systems with two external ports, and the strategies and limitations for conversion of energy from one port into the other. It turns out that, apart from t…
Memcapacitors and Meminductors are Overunity Systems!
Dimitri Jeltsema, Arjan van der Schaft
It is rigorously proved that ideal memcapacitors and meminductors are not passive or lossless devices, nor are they satisfying the weaker notion of cyclo-passivity, which arises wh…
Limits to Energy Conversion
Arjan van der Schaft, Dimitri Jeltsema
A consequence of the Second Law of thermodynamics is that no thermodynamic system with a single heat source at constant temperature can convert heat into mechanical work in a recur…
Load Characterization and Power Conditioner Synthesis Using Higher-Order Elements
Dimitri Jeltsema
It is shown that virtually all nonlinear and/or time-varying loads that generate harmonic current distortion can be characterized in terms of so-called higher-order circuit element…
