摘　　要：针对非隔离DC/DC升压变换器,可通过采用合适的功率拓扑结构,并引入新的滤波方式来有效地提高其功率密度。对Weinberg、填谷式移相全桥以及Super Boost等三种高效升压拓扑进行了同等功率变换情况下的仿真分析,结果表明带纹波抵消支路的耦合电感Super boost拓扑输入输出电流均连续,且具有最高的功率密度。For non-isolated DC/DC step-up converter, its power density could be increased effectively through appropriate topology and a new filter approach. Three topologies of Weinberg, valley-fill phase-shifted full-bridge and Super Boost were simulated under the condition of equally power level. Simulation results show that Super boost topology with a coupled inductor and input current ripple cancellation circuit has the highest power density, together with continuous input and output current.
