Abstract
A multilink power converter with reduced winding voltage is disclosed. In the disclosed embodiments, multiple converters have their primaries or their outputs connected in series while using a single transformer winding connected to the converters' outputs through voltage blocking capacitors.
Claims12
A device for converting electrical power between an input voltage and a secondary isolated load, comprised of:
- a high or medium frequency transformer comprising:
- a high or medium frequency primary transformer winding comprising:
- a first terminal;
- and
- a second terminal;
- a secondary transformer winding connected to the secondary isolated load;
- and
- a plurality of primary switch modules connected in series across the input voltage,
- wherein each primary switch module in the plurality of primary switch modules comprises:
