A non‐isolated step‐up common‐ground cost‐effective microinverter for AC‐module application
This research proposes a cost‐efficient microinverter. The proposed microinverter can eliminate the leakage current using common‐ground configuration. It uses three switches and only one of them operates at high frequency. In addition, a passive lossless

Lithium ion batteries have a very wide application range. They can power up small electronic devices such as smart watches to larger electric vehicles. Due to its varied range of applications, they come in different packaging and in such battery packs, even when individual cell voltage exceeds by a few milli‐volts above 4.2 V, it may result in thermal ...

(1) This paper proposes a novel interleaved ultra‐large gain zero‐voltage switching (ZVS) DC–DC converter for renewable energy systems. (2) By using coupled inductor (CI) and built‐in transformer (BIT), a high‐voltage gain is achieved. (3) The secondary windings of the CIs are connected in series with the primary winding of the BIT and the secondary ...

An interleaved high step‐down coupled inductor based quadratic DC‐DC converter
A high step‐down DC‐DC buck converter with a coupled‐inductor in its topology is presented in this study. The switching pattern of the proposed converter is interleaved; therefore, the voltage stress on the semiconductors and the components is low since the primary high voltage will be divided between the blocking capacitors on the primary side ...

Combining electric vehicle battery charging and battery cell equalisation in one circuit
Abstract Electric vehicles (EVs) require an onboard battery charger unit and a battery management system (BMS) unit that balances the voltage levels for each battery cell. So far, both units are two completely autarkic power electronics systems. The circuit presented here operates as a battery charger when the EV is connected to the grid and as a ...

Soft‐switching non‐isolated high step‐up three‐level boost converter using single magnetic element
Abstract Here, a soft switched three‐level boost converter with high voltage gain is proposed which is suitable for high step‐up applications with wide output power range. In this converter, a ZVT auxiliary circuit is used which provides soft switching in a wide range of output power independent of load variation.

Abstract In this paper, a non‐isolated coupled‐inductor high step‐down converter with extended duty cycle is proposed, which operates under discontinuous conduction mode. The soft‐switching condition is provided for all the switches and diodes, which results in the reduction of the switching losses, and the losses related to diode reverse recovery ...
