【摘要】：針對現(xiàn)有電流互感器取能電源存在供電死區(qū)的現(xiàn)象,提出了一種可適應(yīng)較小電流電力母線的電流互感器取能電源供電方案。在分析電源取能原理的基礎(chǔ)上,建立了電流互感器取能電源的電路模型,并推導(dǎo)了電源取得最大功率的條件。選擇高飽和磁感應(yīng)強(qiáng)度的硅鋼材料作為鐵芯,設(shè)計(jì)了五級電荷泵電路、能量收集電路以及電源管理電路�；谒岢龅姆桨秆兄屏藰訖C(jī),以無線測溫模塊作為負(fù)載,對樣機(jī)整體進(jìn)行了測試。實(shí)驗(yàn)結(jié)果表明,當(dāng)電流在1~1 000A范圍內(nèi)時(shí),電源工作于非飽和低熱耗狀態(tài)。
[Abstract]:In view of the phenomenon that the existing current transformer energy-taking power supply has a dead zone, this paper presents a power supply scheme of the current transformer energy-taking power supply which can adapt to the lower current power bus. Based on the analysis of the principle of the power supply, the circuit model of the current transformer energy-collecting power supply is established, and the condition of obtaining the maximum power of the power supply is deduced. Five-stage charge pump circuit, energy collection circuit and power management circuit are designed by selecting silicon steel material with high saturation magnetic induction strength as iron core. The prototype is developed based on the proposed scheme, and the whole prototype is tested with the wireless temperature measurement module as the load. The experimental results show that when the current is in the range of 1 000 A, the power supply works in the state of unsaturated low heat consumption.
