功率VMOS管驅(qū)動(dòng)的直流電機(jī)無(wú)級(jí)調(diào)速系統(tǒng)

摘要：傳統(tǒng)的直流電機(jī)調(diào)速大多采用電阻壓降、雙極性管和晶閘管驅(qū)動(dòng)的方法，但是效率較低，不夠穩(wěn)定。本文介紹了由開(kāi)關(guān)電源供電、大功率VMOS管驅(qū)動(dòng)、脈寬調(diào)制的直流電機(jī)無(wú)級(jí)調(diào)速系統(tǒng)的設(shè)計(jì)，分析了系統(tǒng)的工作原理，實(shí)現(xiàn)了無(wú)觸點(diǎn)、高效率、穩(wěn)定的正反轉(zhuǎn)調(diào)速。 敘詞：脈寬調(diào)制(PWM) 數(shù)字電路 無(wú)觸點(diǎn)正反轉(zhuǎn) Abstract：Most of todays traditional DC-motor speed regulation systems are driven by resistance, bipolar and thyratron, which have deficiency in stability and efficiency. To solve these problems, this article have introduced a design of the DC-motor speed regulation system for the conveyor line powered by Multi-Output switching power, driven by power field effect transistor (VMOS) and controlled by PWM driver program which would realize the non-contact positive and negative rotation control. Having analysed the principle of this system, we have implement the non-contact positive and negative rotation control stably and efficiently. Keyword：PWM, Digital circuit, Non-contact positive and negative rotation.
