Abstract:
1. A method for determining, without measuring, an operating characteristic of a DC/DC power converter for an automotive vehicle including a power storage unit and a bus wherein the DC/DC power converter has a storage side electrically connected with the power storage unit and a bus side electrically connected with the bus and wherein the DC/DC power converter includes a first capacitor, having a first voltage, electrically connected with the storage side and a second capacitor, having a second voltage, electrically connected with the bus side, the method comprising: determining a duty cycle of the DC/DC power converter; measuring one of the first and second voltages; and determining, without measuring, the other of the first and second voltages based on the duty cycle and the one of the first and second voltages thereby determining the operating characteristic of the DC/DC power converter.
