在脉冲电路设计中,需要根据实际应用的波形要求和负载特性选择、设计其电路构型.工程设计中常用的时域波形叠加和参数扫描等波形构型设计方法存在较大局限性,难以形成对脉冲波形构型的物理本质、脉冲电路结构对负载的适应性等方面的系统认识.从分析影响脉冲波形构型的基本要素入手,从时域和频域角度对脉冲波形构型及其电路实现方法进行系统的分析和归纳,给出时域和频域的电路构型设计方法及相应的电路参数解算方法,使设计人员可采用解析分析方法判断电路中元器件参数的调整方向,同时推动电路设计创新.%In the design of pulsed circuit,the configuration of the output pulse waveform and the corresponding structure of the circuit need to be chosen according to the requirements of its application.The design methods of the circuit usually applied in engineering-such as the time-domain waveform superposition and the comparison by parameter-scanning-have a lot of disadvantages in practice,such as making it difficult for the designer to understand the essences of the configuration of the output pulse waveform.In this paper,the design methods of the pulse waveform both in time-domain and frequency-domain are summarized,and the calculation methods of the parameters of the components based on the analysis of the essential characters of the waveform of the circuit output pulse are introduced.The design methods based on the analysis of the frequency domain could help the researcher estimate the parameters of the components by analytic calculation and promote the innovation of circuit design.
