摘要 从电力电子系统的底层脉冲组合理论出发,对功率脉冲时序组合与逻辑组合的概念、方法和实现进行总结提炼分析。针对功率脉冲纯时序组合的局限性,提出功率脉冲及功率脉冲序列的逻辑组合方法,并对其组合思路和应用场景进行分析归纳。由于基于不同脉冲逻辑组合思路的两种典型应用,即多电平技术和倍频策略,均可以有效提高系统变换性能,以电力电子功率放大器为分析对象,对二者的谐波特性和适用性进行对比分析,以此作为上述理论的一个分析应用实例。通过电力电子系统中脉冲组合方法论的研究,有助于从更为底层的角度对相关技术进行系统认识,从而延伸拓展出新的脉冲组合与实现方式,推动电力电子技术的发展。

Abstract:This paper focuses on the basic theories of pulse combination in power electronics. The concept, method and realization of power pulse sequential combination and logical combination are summarized and analyzed. Aiming at the limitations of power pulse sequential combination, the power pulse (sequence) logical combination, as well as the methods and applications, is introduced. Both typical methods based on different pulse logical combination ideas, i.e. multilevel technology and frequency multiplication strategy, are effective in improving the performances of system. Thus, taken the power electronics amplifier as an analysis object, their harmonic characteristics and applicability are compared and contrasted. With the study of pulse combination methodology in power electronics, the relative technologies can be systematically understood, moreover, novel pulse combination and realization methods can be expanded. It is helpful to promote the development of power electronics.
Key wordsPulse sequential combination    pulse logical combination    frequency multiplication strategy    harmonic analysis
