220v降压成5v电路图-220v降压5v简单电路

The topic I interviewed at a company was to draw a circuit diagram of 220V AC to 5V DC. I want to ask if the drawing circuit diagram can not draw this part of the voltage regulator?

我在一家公司面试出的题目是画一个220V转5V输出的简单电源电路图，我想问的是画电路图能不能不画稳压的这一部分？

Of course, you can not draw voltage regulation, because the problem is AC to DC. However, your purpose is not to do the topic, but to go to the interview, I hope to be hired, right? I hope to show your ability and value through this topic, right?

当然可以不画稳压，因为题目是交流变直流。但是，你的目的不是去做题目，而是去面试，是希望能够被聘用，对不对？是希望通过这个题目展现你的能力与价值，对不对？

If you have an innovative design and you can explain your design to the interviewer well, there is no problem with not drawing DC.

如果你有创新的设计，而且你能向面试者很好的说明你的设计，不画直流完全没有问题。

If you don't have any innovations, and don't be meticulous and professional, is it equal to not being able to go with yourself?

如果你没有任何创新，又不做细致一点、专业一点，是不是等于跟自己过不去呢？
