A full-bridge secondary dual-resonant DC-DC converter using the asymmetrical pulse-width modulated (APWM) strategy is proposed in this paper. The proposed converter achieves zero-voltage switching for the power switches and zero-current switching for the rectifier diodes in the whole load range without the help of any auxiliary circuit. Given the use of the APWM strategy, a circulating current that exists in a traditional phase-shift full-bridge converter is eliminated. The voltage stress of secondary rectifier diodes in the proposed converter is also clamped to the output voltage. Thus, the existing voltage oscillation of diodes in traditional PSFB converters is eliminated. This paper presents the circuit configuration of the proposed converter and analyzes its operating principle. Experimental results of a 1 kW 385 V/48 V prototype are presented to verify the analysis results of the proposed converter.

“…Energy recovery clamp circuits (ERCCs) has been proposed to avoid the adverse effect of voltage spikes in the diodes [7]- [9].The ERCC techniques are able to reduce the voltage stress of the output diodes, but in case of ERCC's the amount of the voltage stress will depend on the duty ratio and input voltage of the converter in most of the ERCCs techniques. Some references tried to decrease the leakage inductance as much as possible through the transformer winding structures [10]. These topologies effectively decrease the peak of the voltage spikes across the output diodes.…”

“…Thereby, this decreases the converter efficiency and increases the cooling needs. If synchronous rectifier MOSFETs are used instead of diodes on the bridge rectifier, the converter power losses are reduced, so the converter can be smaller [13]. This feature is called "Synchronous Rectifier" and described in [14].…”

In this paper, phase-shifted pulse width modulation full bridge topologies which are capable of switching at zero voltage are evaluated. Eight examples of these topologies have been studied in detail and compared in different aspects. After a detailed investigation, it has been decided to use zero voltage switching with current doubler and synchronous rectifier phase-shifted pulse width modulation full bridge converter (ZVS-CD-SR-PS-PWM-FB). This converter can be used especially for more load current demand and more compact power supply applications. This topology was analyzed in detail, the design was performed, simulation work was carried out and finally it was tested in detail in the laboratory. The performance of the proposed converter was verified on a 400 W DC-DC converter operating at 100 kHz from 270 VDC input voltage.
