Abstract

See full text

A pre-charging and voltage supply system for a DC-AC inverter is provided. The system includes a first battery having a first anode and a first cathode, and a second battery having a second anode and a second cathode. The system further includes a contactor electrically coupled in series between the first anode and an electrical node. The system further includes a microprocessor that generates a first control signal to induce a DC-DC voltage converter to increase a voltage level between the electrical node and the first cathode. The microprocessor further generates a second control signal to induce the contactor to transition a contact to a closed operational position such that a first voltage level is applied to the DC-AC inverter, if the voltage level between the electrical node and the first cathode is greater than a threshold voltage level.
