摘    要:根据膏体推进剂火箭发动机等离子弧多次点火的设计要求,设计了一种脉冲宽度调制(Pulse Width Modulation,PWM)型引弧器.该引弧器采用单端反激式升压电路、功率型PWM推动,自动检测等离子点火器状态并调整相应的工作模式,实现引弧和稳弧双重功能.试验结果表明其引弧能力强,满足等离子点火器对高频引弧器引弧能力的高要求,达到了设计的最初目的.

Abstract:According to the design requirement of plasma arc multiple ignitions for pasty propellant a kind of power PMW arc starter was designed. The arc starter driven by the power PMW uses single ended backward step-up transform circuit automaticall detects the state of plasma igniter, modifies to be the corresponding working mode, and realizes the double function of starting arc and stabilizing arc. The experiment demonstrates that it has good starting arc capability, satisfies high requirement of plasma igniter for high-frequency arc starter capability, and achieves the initial goal of design.
Keywords:Pasty rocket  Plasma igniter  PWM  Single ended backward transformer  Arc starter
