This article presents a new circuit topology for high voltage gain active switched boost quasi Z-source inverter (qZSI) and pulsewidth modulation (PWM) technique. The higher boosting capability with lower number of elements, the continuous source current, less stress across devices, having common ground are main advantages proposed structure. is twice that conventional capacitor-assisted qZSI (...

In this study, the authors propose a non-isolated high step-up interleaved DC/DC converter that can be applied to sustainable energy system. The proposed achieves voltage gain by applying coupled inductor and switched capacitor method based on an boost converter. two inductors connected in parallel with input side have distinct structure. Specifically, single has primary secondary series output...

The direct current (DC)–DC converter presents abundant nonlinear phenomena, such as periodic bifurcation and chaotic motion, under certain conditions. For a switched-inductor buck-boost (SIBB) with the memristive load, this paper constructs its state equation model two operating statuses, investigates dynamic characteristics, draws analyzes diagrams of inductive phase portraits, some parameter ...

Innovative power electronic converters have emerged because of renewable energy expansion in the past two decades. Direct current DC grids can operate independently or connected to grids. A grid has distributed generation (DG) units, such as solar panels and, fuel cells. It is necessary a DC-DC converter raise output voltage. Boost limited voltage gain, and their switching stress often equal Th...

Cascaded multilevel inverter (CMI) topology is prevalent in many applications. However, the CMI requires switches and isolated dc sources, which main drawback of this type inverter. As a result, volume, cost complexity are increased efficiency deteriorated. This paper thus proposes switched-capacitor-based with half-bridge cells only one source. Compared to conventional CMI, proposed uses almos...

This paper reviews and discusses the state of art integrated switched-capacitor inductive power converters provides a perspective on progress towards realization efficient fully DC–DC conversion. A comparative assessment has been presented to review salient features in utilization transistor technology between switched inductor converter-based approaches. First, applications that drive need for...

The proposed converter remarkably integrates and cells, leading to significant increase in voltage gain. unique composite structure not only ensures the continuity of input current, but also successfully minimizes current ripple stress across components, thereby optimizing efficiency. st...

This paper proposes a single-stage Sepic-type high brightness LED driver for universal line input to perform power factor correcting and LED dimming. In the driver, a coupled inductor is introduced to replace with two separate inductors to lower volume and cost. A soft-switching cell is embedded into the driver to obtain zero-voltage switching ZVS feature so as to furthermore improve driver eff...

Since fuel cells store more energy and batteries supply more power, fuel cell–battery systems can be smaller than single-source supplies. The 0.18-μm CMOS switched-inductor charger–supply shown, for example, draws constant power from an energy source and supplementary power from a battery to supply a 0.8-V load and recharge the battery with excess power. With 62% – 83% efficiency across 0.1 – 8...
