Can the circuit design of a lead-free soldering station be imitated like this? [Copy link]

In a group, I saw someone holding a half-circuit diagram of a Goodheip GD90 lead-free soldering station and asking everyone. He wanted to modify it and make a DIY, but because he only got half of the diagram, he wanted to copy others' things. I don't know if such a circuit diagram is useful. From my personal point of view, it is generally difficult to make a high-quality imitation. Let's not talk about other things. Just looking at this circuit diagram, I feel complicated because I don't make soldering stations. Please ask professional masters to comment on this circuit diagram. If you design it yourself, how would you design it? If he can make a high-quality imitation, can it succeed?

The above is the circuit diagram to be imitated

Putting aside other things, 30V AC input and 48V DC output is very unreliable.

30V*1.4142=42.4V.

The picture you posted is just the front end of a power supply. It doesn't involve the main parts at all and is almost completely meaningless.

How can we talk about imitation or not for such a simple circuit?
