The old problem of controlling transformer burned out

You did not analyze the reasons for the transformer burned, is the primary or secondary fire, which coils? If that is caused by high voltage transformer overheating, then you can set
Share of non-target, such as 400/200, and the low voltage transformer will be no major cases of failure, although this time the voltage switching  power supply may be low, but the ability to adapt to non-switching power supply
So you often strong side to improve power supply voltage rating. The most important thing is you have to analyze the reasons for the transformer burned. Burned when the first should determine the reasons for its failure.
