Renewable energy is derived from natural resources and most commonly used renewable energy system is photovoltaic cells. DC-DC boost converter serves many purposes and usually required in many applications which has a low output voltage such as batteries, photo-voltaic cell. In this paper interleaved boost converter (IBC) topology is discussed for solar energy generation. IBC have better performance characteristics compared to a conventional boost converter due to increased efficiency. DC-DC IBC have been considered and analyzed by input current ripple and output current ripple and output volt

In the present study Ar+ cluster ions accelerated by voltages in the range of 5–10 kV are used to irradiate single crystal ZnO substrates and nanorods to fabricate self-assembled surface nanoripple arrays. The ripple formation is observed when the incidence angle of the cluster beam is in the range of 30–70°. The influence of incidence angle, accelerating voltage, and fluence on the ripple formation is studied. Wavelength and height of the nanoripples increase with increasing accelerating voltage and fluence for both targets. The nanoripples formed on the flat substrates remind of aeolian sand

Abstract Conventional boost converters are widely used for connecting low-voltage power sources and inverters in motor control.

Modular multilevel converters (MMCs) will be widely applied in onboard integrated power systems due to their high levels of electric power output and good-quality sine waveform outputs.

In order to reduce voltage ripples efficiently, a capacitor voltage ripple-suppression strategy employing a reversed PWM switching channel is proposed in this paper.

Abstract:
The voltage and current ripples in the three-level bi-directional converter (TLBC) can be reduced by an interleaving technique that controls a phase difference between the modules of power converter. On the other hand, the inductor current ripple in TLBC is increased due to the circulating current between the modules. In this paper, the effects of two interleaving methods on a two-phase TLBC, Z-type and N-type, are investigated and compared. In particular, capacitor current ripple, and voltage ripple are compared by two interleaving methods verified through Powersim (PSIM) simulation.
