HN 提问：直流供电的家？
2 分•作者: dhosek•3 个月前
我一直在思考这样一个事实：目前的家庭电路布线严重依赖交流电（AC）进行电力输送。这对于电力传输来说是合理的，因为过去一个世纪左右的时间里一直都是这样做的。但是，随着向太阳能和电池储能的转变，我开始思考，家庭电路布线是否应该从120V交流电转向12V直流电（DC）或类似的电压。
由于我在这方面缺乏实践电气工程知识，我想知道这是否可行，以及会面临哪些工程挑战。当然，除了我的厨房，我家里似乎所有设备都在将电力转换为直流电（或者可以轻松修改为使用直流电源运行，比如照明）。而且，也许没有令人信服的理由要求冰箱、微波炉、炉灶、烤箱或其他厨房电器必须使用交流电。

I’ve been thinking about the fact that contemporary home electrical wiring is heavily predicated on AC for power delivery which makes sense for power transmission as it’s been done for most of the last century or so, but with the shift to solar and battery storage, I’m wondering whether it makes sense for in-home electric wiring to move from 120V AC to 12V DC or something similar. Since I’m largely ignorant of practical electrical engineering skills, I’m wondering whether this is something that makes sense and what the engineering challenges would be. Certainly, other than my kitchen, it seems like everything in my house is converting its electricity to DC anyway (or could be easily modified to function with a DC power supply, like the lighting). And perhaps there’s no compelling reason why we need AC for the fridge, microwave, stove, toaster oven or other kitchen stuff.
