CIRCUIT AND METHOD FOR PROVIDING MULTI-MODE ELECTRICAL POWER TO AN ELECTRICAL LOAD IN A VEHICLE

A circuit and method for providing multi-mode power to a vehicle load may include first and second voltage sources, main positive and main negative relays, and first, second, and third relays. The main positive relay may have a second side connected to a first side of the load, and the main negative relay may have a second side connected to a second side of the load. A first side of the second relay may be connected to a positive side of the first voltage source, and a second side of the second relay to a positive side of the second voltage source and a first side of the main positive relay. A first side of the third relay may be connected to a negative side of the second voltage source, and a second side of the third relay to a first side of the main negative relay.
