| Summary: | 碩士 === 雲林科技大學 === 電機工程系碩士班 === 98 === A novel interleaved half-bridge converter with zero-current-switching
(ZCS) is proposed in this thesis. This topology is suitable for application of
high input voltage. This topology is used the inductor and the capacitor to
achieve ZCS function to reduce the switching loss and improve the efficiency.
Reset the transformer to avoid the saturation situation by using the
symmetrical half-bridge topology. Transformer secondary side is use the
full-wave rectification to decrease the current stress of the rectifier
components. The transformer secondary side rectifier components all on ZVS
condition and a part of them have ZCS condition. Therefore, it will be reduce
the switching loss of the transformer secondary side and improve the
efficiency.
Simulation and experimental results are used to verify the proposed
converter can achieve the function of ZCS and the output current is operation
on interleaved. Therefore, the converter with high efficiency and power
density can be obtained.
