摘要
针对户外休闲、野外工作者有时需要应急电源的情况,设计了利用太阳能电池进行充电的多功能电源。将太阳电池组件的能量通过充电控制电路为内置的蓄电池充电储存电能。介绍了电路工作原理,通过调试实现了DC5V、12V、4.15V、AC 220V电压输出。具有蓄电池充电欠压和过压显示及自动断开、5号电池限流/限压充电及充满显示和自动断开、锂电池4.15V快速可调的限压充电等功能。通过逆变实现的AC 220V输出,可为5 W以内电器提供交流电源。USB 5V、DC 12V最大输出电流1A,可根据不同的接口为手机、MP3等小功率电子产品充电或供电。
Outdoor recreation and outdoor workers sometimes need emergency power for emergency, thus we designed the multifunctional power which utilizes solar energy to charge. Through the charging control circuit, solar module charges for the built-in battery. Introduced circuit principle, achieved DC 5 V, 12 V, 4.15 V, AC 220 V voltage output by debugging. The design has the function of storage battery under-voltage,over-voltage display, automatic disconnect, AA battery limited current,pressure charging, filted with display, automatic disconnect and lithium battery 4. 15 V speed adjustable limiting pressure charging protection function. Through the inverter to achieve the AC 220 V output, it can provide AC power for appliances of less than 5 W. The maximum output current of USB 5 V,DC 12 V is about 1 A. According to the different interface,charging or power supply for mobile phone, MP3 and other small power electronic products.
