Energy transfer system configurable between charging mode and powering mode

Abstract

-32- Abstract ENERGY TRANSFER SYSTEM CONFIGURABLE BETWEEN CHARGING MODE AND POWERING MODE An energy transfer system (200), including a configurable energy transfer interface (322), a plurality of sets of inverters (312, 314, 318, 320), and a three-winding transformer (308), is disclosed. The configurable energy transfer interface includes a plurality of switches (336, 338, 352, 354, 368, 370, 372) coupled to DC voltage outputs of the plurality of sets of inverters. The plurality of switches is capable of connecting the DC voltage outputs of the plurality of sets of inverters to provide a first DC output voltage and a second DC output voltage for charging batteries of a work machine (100). The plurality of switches is also capable of connecting the DC voltage outputs of the plurality of sets of inverters in series to provide to provide high DC voltage output for operating the work machine. -32- Abstract ENERGY TRANSFER SYSTEM CONFIGURABLE BETWEEN CHARGING MODE AND POWERING MODE 20 26 20 04 25 21 J an 2 02 6 A b s t r a c t 2 0 2 6 2 0 0 4 2 5 2 1 J a n 2 0 2 6 E N E R G Y T R A N S F E R S Y S T E M C O N F I G U R A B L E B E T W E E N C H A R G I N G M O D E A N D P O W E R I N G M O D E FIG. 1 100 102 104 108 106 110 112 118 114 116 120 126 128122136 130 132 134 138 140 124 142 144 1 / 7 100 Z 122 X 136 128 Y 0 144 00 130 108 00110 134 106 0 0 10b 114 116 138 0 0 120 102 20 26 20 04 25 21 J an 2 02 6 J a n 2 0 2 6 2 0 2 6 2 0 0 4 2 5 2 1 1 0 4 Y 0 0 1 3 0 0 0 1 3 2 1 3 4 1 0 6 0 0 1 1 4 1 1 6 1 3 8 0 1 4 0 0 1 2 0
