DC-AC - PRE-CHARGING AND VOLTAGE SUPPLY SYSTEM FOR A DC-AC INVERTER

摘要

A pre-charge 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 the second battery has a second anode and a second cathode. The system further includes a contactor electrically coupled in series between the first anode and the electrical node. The system further includes a microprocessor, wherein the microprocessor generates a first control signal that directs the DC-DC voltage converter to increase the voltage level between the electrical node and the first cathode. The microprocessor is further configured to cause the contactor to apply a first voltage level to the DC-AC inverter when the voltage level between the electrical node and the first cathode is greater than the threshold voltage level, To a closed operating state.
