Abstract
This paper discusses a half bridge converter
with dual outputs.. Two independent regulated outputs are obtained with a single leg consisting of two switches. One of the two outputs is regulated through
the switching frequency of an LCC resonant converter and the other output is controlled through duty cycle by asymmetrical pulse width modulation. The outputs are
regulated over a wide range of input voltages and load variations. Cross regulation between the outputs is minimal due to independent control of each output.
ZVS is also realized by the nature of the topology and higher switching frequencies are possible. The simulation and experimental results obtained for a
converter with 48V input and 12V/20A and 5V/10A outputs are discussed.
