Phase-shift full-bridge (PSFB) Dc/Dc converter has been investigated for decade years and many auxiliary techniques and improvements have been proposed already in the foregoing works to overcome its inherent drawbacks, such as narrow ZVS range for the lagging leg switches, large duty cycle loss and primary-side circulation loss with heavy output load. However, the additional loss and cost are always...
This paper presents the detailed optimum design considerations for a presented synchronous rectified soft-switched phase-shift (PS) full-bridge (FB) converter with primary-side energy storage inductor, which is fit for low output voltage and high output current applications. Although this converter can be operated in CCM, BCM (boundary continues mode) and DCM respectively, the optimum analysis and...
This paper presents a synchronous rectified Soft-switched Phase-Shift (PS) Full-bridge (FB) converter with primary-side energy storage inductor, which can be utilized in low output voltage and high output current applications. This converter can be operated in CCM, BCM and DCM respectively based on different designs. However, optimum design consideration indicates that the BCM and DCM operation modes...
An improved zero-voltage and zero-current-switching (ZVZCS) full bridge dc-dc converter is proposed based on phase shift control. With an auxiliary center tapped rectifier at the secondary side, an auxiliary voltage source is applied to reset the primary current of the transformer winding. Therefore, zero-voltage switching for the leading leg switches and zero-current switching for the lagging leg...
This paper studies the approach of derivation of three-level (TL) half-bridge (HB) topology from conventional full bridge DC/DC topology. The derived TL HB topology has same device count and performance as the corresponding full bridge topology, and it is more suitable for high voltage applications. The derivation approach for different control method, i.e. PWM control, frequency control and phase...
