Digital Current Mode Control Algorithms for High-Power Half-Bridge DC/DC Converters

Digitally controlled systems have many well known advantages in comparison to analogue systems e.g. programmability, higher flexibility and modularity, fewer components, lower sensitivity to noise and environment conditions. Theoretically, all analogue control algorithms can be digitalized. But from practical point of view the digitalization often ends up with some major difficulties, which wil...

Impact of Component Losses on the Efficiency of a New Quasi-Z-Source-Based Dual Active Bridge

The paper analyzes the impact of the component losses on the efficiency of the novel DC/DC converter. The converter is a combination of the quazi-Z-source (qZS) network and dual active bridge (DAB). In the analysis the mathematical loss models of the proposed DC/DC converter are derived and efficiency is estimated. Eventually the efficiency is verified experimentally.

A new proof of regularity of weak solutions of theH-surface equation

We give a new proof of a theorem of Bethuel, asserting that arbitrary weak solutions u ∈ W (IB, IR) of the H-surface system ∆u = 2H(u)ux1 ∧ ux2 are locally Hölder continuous provided thatH is a bounded Lipschitz function. Contrary to Bethuel’s, our proof completely omits Lorentz spaces. Estimates below natural exponents of integrability are used instead. (The same method yields a new proof of H...
