Dual Voltage Forward Topology for High Efficiency at Universal Mains

Abstract: This paper introduces a forward converter aimed at the universal mains voltages, i.e., 220–230 Vac and 115 Vac, named the ‘dual voltage forward converter’. The suggested converter has a narrow dynamic range at the universal mains voltages, which results in lower stress on devices, optimal duty cycles, and better overall efficiency. The topology comprises two primary power loops reconfigurable by additional two-state switches and a passive diode, which allows the converter to run in parallel or in series modes … Show more

“…Due to their simplicity, flyback and forward topologies are frequently used in isolated DC-DC converters for low Power Supply Units (PSU) with less than 1 kW. In contrast to the Flyback converter, the forward converter's high-frequency transformer does not store energy, making it more suitable for applications requiring high output current (Ezra et al, 2022).…”

“…In such converters, resonance occurs just before the switching time, providing PWM control for the converter. These converters provide smooth load-independent switching and operate at constant frequencies [37][38][39]. Ref.…”
