Abstract
A single transformer converter which may switchably disconnect all of its converter outputs, or alternatively just some of the converter outputs. In some electronic systems this would allow the turning-off of some units, such as printers, while leaving on other units, such as a CPU or a twenty-four hour clock. Further, an uninterruptible output is provided by the converter to maintain applications and operating systems software stored a CMOS RAM even in the event of a power outage.
