According to the characteristics of the conventional rectifier circuit that there exists a dead area with top wave, the author puts up with a certain control method which follows current by use of the high-frequency soft switch link to make the incoming current close to the sinusoidal wave.
Conventional cascade buck-boost PFC (CBB-PFC) converter suffers from the high conduction loss in the input rectifier bridge. To resolve the above problem, a novel bridgeless buck-boost PFC topology is proposed in this paper. The proposed PFC converter which removes the input rectifier bridge has three conduction semiconductors at every moment. Comparing with CBB-PFC topology, the proposed topology...
In this paper, a novel interleaving control strategy for DC/DC converters is proposed and applied to a new isolated DC-DC converter configuration with two paralleled half-bridge structure at the primary side and a new rectification method at the secondary side of the transformers, aiming at to optimize the design of transformers and reduce the rectifier diodes voltage stresses. The concept of this...
