Triboelectric nanogenerator (TENG), a class of mechanical to electrical energy transducers, has emerged as promising solution self-power Internet Things (IoT) sensors, wearable electronics, etc. The use synchronous switched extraction circuits (EECs) an interface between TENG and battery load can deliver multi-fold gain over simple-minded Full Wave Rectification (FWR). This paper presents detai...

The development of high-frequency power converters is continuously improving their density, efficiency and fast dynamic response. Among them, high-voltage-conversion-ratio (HVCR) dc–dc are widely used in high gain, i.e., step-up/-down or bidirectional applications, such as supply for data center, dc micro-grids, electrical vehicle charging systems, etc. In this article, the current main HVCR cl...

Switched capacitor converters play an important role in various applications power electronics. Voltage equalizers are one of them, and have been applied for partial shading compensation photovoltaic systems. In other works, the switched capacitor, improved with addition a small inductor, becoming resonant converter many advantages compared to capacitor. However, this can still be aspects, rath...

Abstract The major challenges of the high-gain DC–DC boost converters are high-voltage stress on switch, extreme duty ratio operation, diode reverse-recovery and converter efficiency problems. There many topologies that have been widely developed to overcome those problems, especially for solar photovoltaic (PV) power-system applications. In this paper, 20 low-power selected from available lite...

A technique which improves the performance of the boost converter by reducing the reverse-recovery-related losses in the boost switch and rectifier with an active snubber that is implemented with a minimum number of components is presented. This minimum-component-count snubber consists of a snubber inductor, an auxiliary switch, and a rectifier. The proposed technique reduces the reverse-recove...

Abstract: This paper proposed a new type of converter called Single Phase Switched Inductor Z-source Matrix Converter (SLMC). It is an ac-to-ac converter with diode bridge bidirectional switch cell. The limitations of existing matrix converter like voltage regulation and quality output issues are overcome in the proposed SLMC by adding the switched inductance. The simulation is performed for di...

This paper presents research results related to the concept of a high-voltage-gain DC-DC converter with low input current ripple. In proposed topology, low-volume switch-mode boost operates in parallel switched-capacitor voltage multiplier (SCVM). The overall achieves four-fold gain, but stress transistor and diode is only half output voltage. achieved by applying specific topology converter. F...

This paper is focused on the input current in a Switched Mode Power Supply (SMPS) which power inductor exploited up to saturation showing non-linear behaviour. The exhibits distortion due nonlinearity. electromagnetic interference (EMI) caused by ripple at switching frequency, superimposed DC value of current, requires suitable design differential mode (DM) filter. analyzed both time and freque...
