Abstract
Some embodiments include a high voltage direct current (HVDC) power generator system for information technology (IT) racks. The HVDC power generator system can include a three-phase alternating current (AC) transformer having a primary winding and a plurality of secondary windings. A plurality of three-phase bridge rectifier circuits can be electrically coupled respectively to the plurality of secondary windings. The HVDC power generator system can include output terminals for powering its load. A first string of bridge rectifier circuits can be in series with each other and a first inductor. A second string of bridge rectifier circuits can be in series with each other and a second inductor. The first and second strings can be electrically coupled in parallel to the output terminals.
