High step-up dc-dc converters are predominantly used for interfacing low-voltage renewable sources including solar photovoltaic (SPV), fuel-cells, and DC microgrid. Several high gain topologies reported in the literature to integrate such sources, however, suffer from issues as limited voltage boosting factor, higher device stress, inability deal with wide input variations, increased count, discontinuous current, so on. To address aforementioned limitations, this article proposes a modified converter. This is achieved by methodically adjusting Z-source (ZS) converter obtain while lowering stress count. As result, switches lower on-state resistance $(R_{ds(on)})$ employed, which facilitates reduced switching losses enhanced efficiency. Furthermore, drawing continuous has improved efficiency at duty ratios, crucial aspect of an SPV interface The implemented topology performed well when compared similar recent topologies. Eventually, experimental waveforms validate theoretical claims analysis. A 93.5% peak been obtained.

ABSTRACT This paper presents a switched capacitor (SC)‐based common‐ground five‐level inverter for photovoltaic (PV) applications. The connection is formed between the grid neutral and source negative, reducing circuit's concern of leakage current due to PV parasitic capacitance. Moreover, proposed can obtain two‐time boost input voltage by using SCs. Self‐voltage balancing absence requirement precharging capacitors made circuit simple attractive. Further, least disconnection time minimizes magnitude inrush currents in buffer capacitors. only has six switches two diodes realize output with double boosting voltage, making compact low‐cost compared its counterparts.

Generating chaos from originally non-chaotic systems is a promising issue. Indeed, has been successfully applied in many fields to improve system performance. In this work, Buck converter chaotified using combination of the switching piecewise-constant characteristic and anticontrol feedback. For electromagnetic compatibility compliance reasons, feedback control method able, at same time, achieve low spectral emissions maintain small ripple output voltage inductance current. This new implies fast non-linear action MOSFET on period ramp generator. Thus, it essential analyze its thermal why we propose an original analysis influence frequency variation junction temperature: investigate correlation between lifetime power electronic component stress due addition chaos. It appeared that reduction current did not degrade performance, despite MOSFET. Furthermore, degradation was indicated for chaotic behavior versus periodic behavior. leads conclusion produces accumulated fatigue effect semiconductor.
