I recently bout a transformer to clean up my AC line. I thought I was getting 1:1 but it appears that I have 1500 Watt 2:1. It has european 220 Male and North american 110V female. Can I make use of this transformer? What is the best way to use it? Can I connect it to 220 in this house and use the 110 Output?
Probably yes. You will have to work out getting a 240V AC line to your listening room, the correct 240V dual breaker, the correct 240V connector and the safety ground issues.
Going from 50Hz to 60Hz and from 220V to 240V won't phase a power transformer at all.

Hi peoples 😀
im designing a dc to dc converter with a dual polarity (+-30v) (+-6A) output.
i am using an example from Switchmode Power Supply For Car Audio
i just have trouble understanding one thing. please bear with me as i try and explain myself.
The transformer i will wind myself needs two primary and two secondary coils.
i will be applying 12v, 30A(car battery) to center tap of primary and need to get 30v and 6 amps. one for the positive rail and one for the negative rail.
I understand how to get the voltage and current on primary side of transformer. I also understand voltage on secondary of transformer. the only thing im not sure about is how on earth u can get 6A per rail when Faradays transformer equation clearly states:
v1/v2 = i2/i1
so..12A/30V = xV/30A
solving for x i get 12A on secondary.
now 12A cant be spilt to get 6A because i have two secondaries or does it??
then if so does the 30v output split so i get 15v on each rail?????????????
THanks for allowing me to confuse u
any help would be much appreciated

WAJHI,
The way your description reads it appears you are intending to connect DC to the primary and expect stepped up DC on the secondary ?? If so , you will be disappointed as transformers do not work on DC !! If I have misread please ignore 🙂

its ok i understand how it works.
if you look at the link i sent u u would see that this is a step up dc to dc converter incorporating a transformer. so to answer ur question Thermal Runaway yes u can use transformers in a switch mode power supply.
