The model-based methods of maximum power point (MPP) tracking in photovoltaic installations are widely known. One of these methods proposes the use of tracking by direct estimation of the maximum power point resistance using irradiance measurement processing. It proposes six different models for this estimate. In the present work, an exhaustive ana...

The multi-functional converter system (MFCS) is a special topology of three-phase AC motor drives, which inherently integrates a DC-voltage regulation function. Firstly, in order to explain the mechanism of the MFCS, an average model is derived. An equivalent circuit is developed, which explicitly reveals that the MFCS is equivalent to a cascaded D...

Abstract—A basic platform for photodetector modules used in the lidar complex for recording backscattered radiation in the near-infrared region is described. High-voltage pulse noise of DC/DC converters in the photodetector modules are reviewed and tested. A method is proposed for compensating the noise generated by such converters. The tests carri...

This paper proposes an energy shaping controller of a DC/DC converter for automatic guided vehicles (AGVs) wireless power transfer (WPT). A transformer is inserted after the LCC topology to improve the transfer power, and the DC/DC boost converter is added before this topology to obtain desired systematic power dynamically. The system power transfe...

The operational expenditures of solar energy are gaining attention because of the continuous decrease of the capital expenditures. This creates a demand for more reliable systems to further decrease the costs. Increased reliability is often ensured by iterative use of design for reliability. The number of iterations that can take place strongly dep...

In this paper, a novel control circuit that can connect fuel cell (FC) modules in parallel is proposed, which is particularly useful when the employed FCs have different electrical characteristics. Conventional methods (e.g., DC/DC converters) are not applicable in such situations because they cannot regulate the power output of each source in a pa...

This work presents the design and test of a switched-cap 3D DC/DC converter able to work up to 60V. The switches and the control circuits are integrated single-chip in a high-voltage (HV) MOS technology, and the passive devices are stacked on top of the chip. As an innovation versus the state-of-the-art, the work first presents the design of integr...
