針對(duì)交流電路過零檢測(cè)電路存在結(jié)構(gòu)復(fù)雜、過零點(diǎn)檢測(cè)不準(zhǔn)確、編程繁瑣等問題，設(shè)計(jì)了一種基于LM339的硬件結(jié)構(gòu)簡(jiǎn)單的過零檢測(cè)電路。通過仿真軟件Mulisim對(duì)該設(shè)計(jì)電路進(jìn)行了仿真，實(shí)驗(yàn)證明了該方案過零檢測(cè)的可行性、穩(wěn)定性和可靠性，可直接作為交流電路中CPU的過零信號(hào)。Aiming at the problems of AC cilsuit zero crossing detection circuit such as complex structure, zero crossing detection and cumbersome programming, a zero crossing detection circuit with simple hardware structure based on LM339 was designed. The design circuit was simulated by simulation software Mulisim, and the feasibility, stability and reliability of zero crossing detection were proved by experiments, which can be used as zero crossing signal of CPU in AC circuit directly.
