| Abstract |
The locomotive battery requests its testing system
special requirements of excellent DC charge/discharge
current which is sensitive to the fluctuation of the voltage. It
also needs a fast transfer speed between charge and
discharge state. Simple converters without appropriate filter
can’t meet the requirement mentioned above. The decay of
the Chebyshev filter increases fast with frequency in the
stop-band. As a low-pass filter, it avoids the influence to DC
component when filtering low order harmonics. It is very
benefit in filter design for bidirectional converters. But the
traditional theory for filter-order design is based on the
decay of not only stop-band but also pass-band, and the
latter is not important in DC filter design. This paper
extracts an equation of filter-order design for bidirectional
converters which care more on the decay in stop band and
introduced a method for enhance the response speed
between bidirectional transitions. The theoretical deduction
and simulation proved the practicability of the methods. |
