Resumo(s)
This paper describes a new configuration of Cuk and SEPIC (Single-Ended Primary Converter) ZVS-QR (zero-voltage switching quasi-resonant) combination DC-DC converter for bipolar
output with a single switch. The proposed topology employs a single ground-referenced power
switch, which simplifies the gate drive design with a single L-C resonant network and provides a
bipolar output voltage with good regulation, acceptable efficiency and a step-down/up conversion
ratio. This configuration provides dual-output voltage by switching the power switch to zero voltage,
which is an interesting alternative for many applications where small size, light weight and high
power density are very important aspects. In order to verify its performance, a SEPIC–Cuk Combination ZVS-QR prototype with a cost-effective commercial resonant controller was designed and tested.
The experimental results show that the proposed combined topology is suitable for Single-Input
Dual-Output (SIDO) applications.
