PARALLEL OPERATION SYSTEM HAVING MINIMIZED FILTER
Document Type and Number:
WIPO Patent Application WO/2019/039638
Kind Code:
A1
Abstract:
A parallel operation system having minimized filter according to the present invention allows the number of filters for filtering output to be reduced to one and thus reduces the volume and unit cost of a power converter even if the number of PWM control power converters, which are for interleaved-type parallel operation by means of a DC-DC converter, is increased to two or more, and enables railway vehicle operation by means of a remaining DC-DC converter which does not malfunction even if some products among DC-DC converter products of a railway vehicle electric power system malfunction.
