Abstract
A vehicle includes a traction battery, an electric machine, and a variable voltage converter. The variable voltage converter includes an inductor and is disposed electrically between the traction battery and electric machine. The vehicle also includes a controller programmed to issue duty cycle commands for the variable voltage converter based on a product of an AC component of current flowing through the inductor and a calibrated resistance.
