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 first cathode is electrically isolated from the second cathode. The system includes a contactor coupled in series between the first anode and an electrical node. The system includes a microprocessor that generates a first control signal to induce a DC-DC voltage converter to increase a voltage level applied to the DC-AC inverter. The microprocessor generates a second control signal to induce the contactor transition to a closed 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."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Pre-charging and voltage supply system for a DC-AC inverter","description":"A pre-charging and voltage supply system for a DC-AC inverter is provided.
