Dual-output boost converter

Abstract

In this paper, a dual-output boost converter with positive and negative output voltages under a single positive voltage source fed. Due to its dual output with positive and negative output voltages, this converter is very suitable for driving the half-bridge class-D amplifier, so as to remove a DC blocking capacitor required in the half-bridge class-D amplifier. Firstly, the basic operating principles of this converter are illustrated along with a simple mathematical deduction, and eventually some experimental results are provided to demonstrate its effectiveness.Keywords-Dual-output boost converter, positive and negative output voltages.

High step‐up isolated dc–dc converter with single input and double output and soft‐switching performance for renewable energy applications

“…Hence, some other converters have been presented to increase voltage gain ratio. A single‐input multiple‐output converter [13] and a dual‐output boost converter with positive and negative output voltages [14] have been investigated. Due to the use of coupled inductors, voltage gain of these converters are high enough to overcome the problem of low output voltage in renewable energy sources.…”
