I changed the transformer in imp.bp to a more powerful one - it doesn’t start, what’s the matter?

Question

Electronics

I took a Chinese power supply, an impulse. I changed the transformer there to a more powerful and overall one, stopped working, tried to change the phasing of the primary windings and swap them, it won’t start. The native transformer is very small - do not wind the vario. What could be the reason? I only changed the trans.

Answer 1

what does more powerful mean? Turns, windings, inductance, core gap?

Answer 2

It seems to me that only instrumental debugging (multimeter, oscilloscope, etc.)
will help here.

postimg.org/image/hi81j9h6lNokia's latest impulse charger. In short, I decided not to install the trance for now, I just want to pull out the alternating current from the output of the trance. The company is not at hand, I drew from the phone as best I could. In short, a blue line in a blue circle is a secondary tratrans, but it’s not clear if it’s one or two of them. The goal is to get alternating current. I threw out two resistors on the left, two yellow dots are a polar capacitor, on the right is a white arc, there is a diode. So, the left secondary --- goes directly to the output to the consumer, closed by a capacitor, threw out the resistors. On the right, the secondary is closed by a diode and closed by a conder + resistor connected in series. As soon as I solder the capacitor, the current disappears at the output, I solder the resistor, too, put a wire instead of the resistor, it doesn’t work. Okay, we can assume that all four pins are the same winding, IMHO at the output we have a direct current from the left two contacts without a diode, therefore it is rectified by the diode on the right. The question is - if it's all one winding, only a diode is embedded there, then you need to stick a wire in place of the diode, solder the capacitor and all the resistors - there should be an alternating current at the output, but it's not there, why? I tried to cling the load to the output before turning on the resistors, I dropped out the resistors, there is no load to start. How can I remove AC from it? What will happen if I connect a large trance there instead of the native one, will it work without selecting resistors and conduits for it under the generation winding ?. What will happen if I put on the Old trance and get a change and feed it a similar high-frequency trance for an increase - will the generation in the native trance fade?
