如何用HIP4082设计一个独立电池DC-DC转换器

如何用HIP4082设计一个独立电池DC-DC转换器:The advent of the personal computer (PC), has created the
need for uninterruptible power supplies to insulate computers
from line dips and temporary outages that plague PC
reliability. In addition, numerous other applications exist for
DC to AC inverters including small tools or accessories from
a DC battery source in automobiles. There is a need, too, for
providing battery backup in the telephone industry for 20Hz
ring generators.
The HIP4082 DC/AC Evaluation Board (subsequently referred
to as the “eval-board”) featuring the HIP4082 is one way to
increase the performance, while reducing cost of DC to AC
conversion. The topology chosen uses the HIP4082 to
provide a 60kHz, low voltage, square-wave to drive a small
isolation power transformer. The output of this transformer is
rectified, filtered, and the high voltage inverted again to
produce the desired low frequency (55Hz) output waveform.
(55Hz was chosen as a compromise between the 50Hz and
60Hz power standards.) A variable duty-cycle quasi-squarewave
output waveform was chosen over a sinusoidal
waveform for simplicity and cost-effectiveness. The 60kHz
frequency of the primary-side inverter minimizes cost and size
of the transformer, while the square-wave output waveform
minimizes the size of the secondary-side rectifier filter.
