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.

Abstract This article proposes a design of a multiphase BUCK-type DC-DC voltage converter. This buck converter allows for a high input voltage range from 3 V to 22 V and integrates two voltage modes, namely pulse width modulation control and input feedforward synchronous buck PWM control, to control dual independent voltage regulators or two-phase single output regulators. This type of step-down converter adopts multiphase cascade technology, which can effectively reduce output voltage ripple and increase output current.

This paper introduces a reference-free, scalable, and energy-efficient dynamic voltage scaler (DVS) that can be reconfigured for multiple outputs. The proposed DVS employs a novel swapping switched-capacitor (SSC) technique, which can generate target output voltages with higher resolution and smaller ripple voltages than the conventional voltage scalers based on switched-capacitors. The proposed DVS consists of a cascaded 2:1 converter based on swapping capacitors, which is essential to achieve both very small voltage ripple and fine-grain conversion ratios.

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.

So we need to rectify the ripple and introduce the snubber capacitor to reduces the voltage spike and to improve the efficiency of the system. And also include the increased level of multistage inverter topologies is to extract the maximum voltage without ripple, total harmonic distortion.. The maximum efficiency will achieve up to 94%.

Typical voltage mode-controlled DC–DC converters with single-inductor dual-output (SIDO) in pseudo-continuous conduction mode (PCCM) have slow load transient performance, and cross-regulation still exists between their two outputs.

This paper proposes a method for minimizing the inductor current ripple of a DC–DC converter in a two-stage power conversion system consisting of a grid-connected PWM converter and an interleaved multiphase three-level DC–DC converter. To reduce the output voltage ripple, the three-level DC–DC converter is configured in parallel and operated interleaved. However, a circulating current generated by the interleaved operation increases the inductor current ripple of each DC–DC converter and causes system loss and inductor saturation.

The voltage increasing circuit using the Cockroft-Walton method has a large output voltage ripple and voltage drop. Meanwhile, half wave and full wave rectifier circuits are only capable of producing a DC output voltage and do not reach the maximum voltage value. In addition, the load resistance at each input power saturation is different and high frequencies require the addition of a capacitor circuit.
