| description | High boost DC/DC voltage conversion is always indispensable in a power electronic
interface of certain battery-powered electrical equipment. However, a conventional boost converter
works for a wide duty cycle for such high voltage gain, which increases power consumption and
has low reliability problems. In order to solve this issue, a new battery-powered combined boost
converter with an interleaved structure consisting of two phases used in automotive audio amplifier
is presented. The first phase uses a conventional boost converter; the second phase employs the
inverted type. With this architecture, a higher boost voltage gain is able to be achieved. A derivation
of the operating principles of the converter, analyses of its topology, as well as a closed-loop control
designs are performed in this study. Furthermore, simulations and experiments are also performed
using input voltage of 12 V for a 120Wcircuit. A reasonable duty cycle is selected to reach output
voltage of 60 V, which corresponds to static voltage gain of five. The converter achieves a maximum
measured conversion efficiency of 98.7% and the full load efficiency of 89.1%. |
