【Abstract】 In order to meet the requirements of piezoelectric ceramic driving power,a driving power of four interleaved boost converter cells was proposed in this paper based on the interleaved boost driving power with coupled inductors.The four boost converter cells of this driving power could share the input current,so this circuit had small input current ripple.This topology also could reduce the output voltage ripple,and meet the requirements of piezoelectric ceramics driving power for high stability,low ripple and high efficiency.The operating principle of four interleaved boost converter cells was analyzed,and by simulation of saber software,a 2.5 kW hardware circuit based on this topology was built.The simulation results and the results comparison with the interleaved boost converters with coupled inductors demonstrate the feasibility and merits of drive power.更多还原
