This paper proposes a modular isolated dc-dc converter, based on the input-series and output-series (ISOS) association of the full-bridge PWM (FB-PWM) dc-dc converter with capacitive filter. The main attribute of the proposed architecture is its ability to provide self-balance of the input and output voltage across the individual converters, without voltage loop control scheme, both in the steady state and transient operations. Circuit operation, theoretical analysis and modeling are included in the paper, along with experimental results taken from a laboratory prototype with four modules, 1600 Vdc total input voltage, 1600 Vdc total output voltage, 4 kW output power, and 40 kHz switching frequency. Possible applications include high voltage power supplies, solid state transformers, dc current distribution systems, and renewable electric energy systems.

“…Therefore, topologies with high switching frequencies were used to reduce the charging current ripple and extend battery life. However, as the switching frequency increases further, switching losses and EMI noise arise [3][4][5][6]. To solve this problem, the switching frequency is increased by reducing the switching losses through a modified series-loaded resonant converter.…”

A novel battery-operated electronic ballast of fluorescent lamps for photovoltaic applications is presented in this paper. In order to reserve the electrical power transformed from photovoltaic modules, a battery charger with high performance, low switching losses, low cost and high efficiency should be designed. This paper presents a novel battery charger with electronic ballast which is characterized with simple structure, less component count, small volume, light weight, low cost, high efficiency and high power density. Moreover, the electronic ballast uses a current-sourcing push-pull resonant inverter to supply a 40W fluorescent lamp. This new electronic ballast structure can accept 12V DC voltage input to provide the power that the lamp needs. Derivation and operating principles of the proposed topology are performed. All switches in the system can achieve zero-voltage-switching. Experimental results show the functionality of the overall system as well as prove it to be a good solution for several photovoltaic applications.

A high-voltage dc-dc converter with low voltage stress nonlinear relationship that ro x BVk where k E [1.6, 2.6]. on the switches and output current tripler is presented in this paper. This converter exhibits three distinct features. First, the This leads power electronics designers to explore new voltage stress on the switches is only one-third of the input converter circuits that can reduce the device voltage voltage, so that switches of low voltage rating and thus of low on-requirement, so that switches of low on-resistance can be used. resistance can be used. This can reduce the conduction loss.As shown in Fig. 1, a typical dc-dc converter consists of Second, all switches are soft-switched, so that the switching loss two power conversion stages. The first stage, the dc-ac can be reduced. Third, the output circuit is a current tripler, so converter, generates a high-frequency (HF) ac voltage that that the output current capacity and thus the power handling drives a transformer. The transformer is used for electrical capacity of the converter are increased. A 4.8kW, 1000V/48V dcisolation and providing an output voltage as determined by dc converter prototype has been built and tested. Experimental the turns ratio. The second stage, the dc-ac converter, consists results are favorably compared with theoretical predictions. of rectifiers, output filters, and snubbers.
