TLDR
In this article, a two-output DC-to-DC converter is studied using only a power transistor, and both outputs have been regulated by controlling duty cycle and switching frequency.Abstract:
A novel two-output DC-to-DC converter is studied. Using only a power transistor, both outputs have been regulated by controlling duty cycle and switching frequency. The number of power components is very low, as the use of demagnetizing components of the isolation transformer is avoided. A static and dynamic study of the converter has been carried out, and the results are verified for a prototype. >read more
