How to increase currents of a transformer
DIY Electronics
If your the transformer too low current, until you cannot use fully it. It is a pity if you need buy the new transformer. So let’s look at how to modify it to increase current up. But the transformers must be the center trap type as Figure 1, suppose your circuit need the 9V AC voltage only. You need to use 2 terminal are lead 9V and OV. Figure 1 inside transformer have the center trap terminal How to modify it. To begin with, remove a paper that wrap a coils out, will be noted that the CT or OV …
Automatic Reverse polarity switch by Relay.
Basic Circuits
This circuit is an automatic reverse polarity switch. If we apply DC voltage to a any electronic circuits in wrong polarity. It can be caused by too much current. You must waste time to reverse the new terminal. If your circuit is importance, let’s build this project to your life will better. How it works In Figure 1. We apply the DC voltage to input in the correct polarity. Secondly, the forward current flow through a diode to the relay’s coil. Then, the relay pull in the positive voltage input from the lead C/1 flow to lead NO/1 that is …
