Output Considerations

Paralleling and Series Converter Connections

The outputs of like converters may be connected in parallel without damage. However, they will not share the output load to any guaranteed extent without some ballasting resistance or external circuitry. A proven circuit for forcing current sharing of three low voltage 80 watt converters is shown. This circuit may be extended to four or more converters.

When sharing power at a higher output voltage, converter outputs may be connected in series. For example, two 80 watt converters each delivering 14 VDC on their output may be connected in series to provide 160 watts at 28 VDC. Series converters always share output current. Power is shared to the extent of the (excellent) voltage regulation.
