This paper considers a single-phase grid-connected converter in the presence of non-linear loads. A local voltage support strategy is proposed to compensate the harmonics caused by the loads. This is an added feature implemented in parallel with a conventional current control method, and distinctively, it does not need measurements of the grid or load current. The converter output current consists...
A scheme is presented to integrate a primary-side-sensing technique into a model-predictive-controller for a Flyback converter. The control circuit consists of a signal processor, an observer, and a model-predictive controller. Besides inheriting the advantages of model-predictive-control, e.g. optimal tradeoff between overshoot, fast stabilization and constraints handling, the proposed controller...

Feedback sensor isolation is often an expensive necessity in power converters, for reasons of safety and electromagnetic compatibility. A disturbance observer-based control strategy for a dual-output resonant converter is proposed to overcome this problem. Current control of two LED loads is achieved through estimation rather than measurement. Robustness against temperature changes, which have significant...
