A Voltage Multiplier Circuit Based Quadratic Boost Converter for Energy Storage Application

Abstract

In this paper, a new transformerless high voltage gain dc-dc converter is proposed for low and medium power application. The proposed converter has high quadratic gain and utilizes only two inductors to achieve this gain. It has two switches that are operated simultaneously, making control of the converter easy. The proposed converter’s output voltage gain is higher than the conventional quadratic boost converter and other recently proposed high gain quadratic converters. A voltage multiplier circuit (VMC) is integrated with the proposed converter, which significantly increases the converter’s output voltage. Apart from a high output voltage, the proposed converter has low voltage stress across switches and capacitors, which is a major advantage of the proposed topology. A hardware prototype of 200 W of the proposed converter is developed in the laboratory to validate the converter’s performance. The efficiency of the converter is obtained through PLECS software by incorporating the switching and conduction losses.

Topology-Mediated Molecule Nucleation Anchoring Enables Inkjet Printing of Organic Semiconducting Single Crystals for High-Performance Printed Electronics

“…Notably, the high μ ave and low CV μ of the FET array are favorable for constructing large-scale and complex integrated circuits. As a proof-of-concept demonstration, we developed a binary ratio multiplier, which is an indispensable functional unit for a convolution algorithm in the neuromorphic chip, based on the patterned C 8 -BTBT single crystals (Figure g). − The multiplier circuit integrated five FETs and was composed of a pseudo-CMOS inverter and a NAND gate (Figure h). In the multiplier circuit, the bottom gate electrodes were patterned by a shadow mask; the semiconductor layers of C 8 -BTBT single crystals were deposited and patterned by the method described in this work, followed by the thermal evaporation of the top electrodes.…”
