Hi all, I’m struggling with understanding a full-bridge transformer-isolated boost converter. The author mentions that during the first subinterval, Q1, Q2, Q3, and Q4 are all on at the same time, leading to transformer saturation. However, I don’t understand why the transformer would satu...
A 48V/100W prototype DC-DC converter has been tested for the verification of the principles. Both simulations and experiments verify the feasibility and advantages of the new topology. Keywords- current-fed; PWM; deadtime; full-bridge; halfbridge in the whole operating period. We call it no ...
converter gain characteristics are the same as traditional isolated full-bridge boost converter.Active-clamp technology is applied in the primary side, which limits the voltage stress of all power transistors within the maximum input voltage of the converter.Resonant voltage doubling network is applied ...
A PFC AC/DC power supply that employs an isolated boost full-bridge (EBFB) converter for PFC with noncascaded connection to a buck-boost converter for voltage regulation is described. A prototype of the proposed power supply is constructed and the experimental waveforms are given. 展开 ...
A Novel Soft-Commutating Isolated Boost Full-Bridge ZVS-PWM DC–DC Converter for Bidirectional High Power Applications A soft-commutating method and control scheme for an isolated boost full bridge converter is proposed in this paper to implement dual operation of the well-... L Zhu - 《IEEE...
1. An isolated boost converter for driving an output load, comprising: an input voltage source; a boost inductor connected in series with the input voltage source; a storage capacitor which receives energy from the input voltage source, the storage capacitor having a first terminal and a second...
In this paper, a new pulsewidth modulated gating scheme and a zero-voltage transition (ZVT) auxiliary circuit is proposed for a fixed frequency full-bridge CLL dc–dc resonant converter with a capacitive output filter. An approximate complex ac circuit app 关键词: Resonant converters Zero voltage...
From the above table, we can briefly summarize the tradeoffs in using a full-bridge vs. half-bridge DC-DC converter topology. The full-bridge topology can access higher output power than a half-bridge topology; for the two to be equal you might need to use parallel FETs in the half-brid...
