| Abstract: | A new power supply schema improved with easy design and reliable performance is proposed which accord-ing to shortcomings of LLC series resonant as low efficiency in light load,circuit design complexity,unstable output voltage and hard to control EMI and so on.The schema based on the series resonance configuration(SRC) combines with synchronous rectification(SR),adopts the zero voltage switching(ZVS) and adjusts the working conditions to re-alize the design of high efficiency power.By means of experiment,th... |
