摘　　要：文章分析了传统Boost电路在实际应用中存在的问题,提出了一种改进型的交错并联Boost电路。在电感电流连续模式下,根据占空比大于或小于0.5的情况,详细分析电路的工作过程,推导了稳态情况下输出输入电压关系式,最后通过仿真验证了理论分析的正确性。This paper analyzes the problem of traditional Boost circuit,and proposes a improved interleaved Boost circuit which incorporates with a multistage capacitor.In the continuous mode,according to the duty cycle larger or less than 0.5,a detailed analysis of the working process of the circuit is made.Under the steady-state situation,the input-output voltage relationship have been investigative.Finally,the simulation certifies the correctness of theoretical analysis for the circuit.
