ABSTRACT
Most power supplies and power electronics circuitries are designed to meet some or all of the following requirements [1]-[5]:
Electrical isolation: The primary advantage of electrical isolation is that the input and output are not electrically connected. If the input supply is ground, the same ground will not be present at output. The transformers utilized in these structures provide two important functions. One is to provide isolation. The other is to step down or step up the time-varying voltages and currents. In addition, by utilizing a very high switching frequency the size of the transformer can be minimized.
Regulated output.
Multiple outputs provide the possibility of feeding different loads simultaneously.
