Abstract:

In this paper, a novel circuit for realizing voltage-mode first-order and second-order all-pass filter responses as well as second-order notch filter response depending on the passive component choice, is presented. This circuit has high input impedance; thus, it is easy to cascade the introduced filter with other voltage-mode topologies. Also, it uses a single Variable Gain Current Conveyer — VGCCII and only grounded capacitors. SPICE simulation results based on 0.35 μm TSMC CMOS technology parameters are given to confirm the theory.

Nevertheless, those topologies show a reduced duty-cycle range, leading to output voltages in the buck region, and thus require the use of very low duty cycles to achieve the lower range of buck output voltages.

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 and increase the performance over the full universal mains range of 90–265 Vac.

The proposed converter provides high voltage gain and soft-switching operation of all semiconductor devices. A voltage doubler and a coupled inductor increase the voltage gain. Zero-voltage-switching (ZVS) of all switches and zero-current-switching (ZCS) of all diodes are achieved. Also, the voltages across the semiconductor devices are effectively clamped. Due to the soft-switching operation of all switching devices, the switching loss is significantly reduced and the high efficiency is obtained. Th
