#137973 - Transformers Responding to: ???'s previous message |
In the links I gave you, there is calculations for the transformer. How does the circuit of your power supply correlate to the example given in the onsemi datasheet? The transformer is a crucial component, you will have to add turns on the primary for the lower voltage. This can be done as a percentage of the original turns - if you want to drop the input voltage by 25%, add 25% of turns to the primary. Be careful when dis-assembling the transformer - there may be a thin spacer in between the E & I ferrite - this is critical, make sure you replace it. I suggest you do some reading on the design of transformers so you understand what you're doing. |
