Abstract
A dual active bridge (DAB) converter includes a variable inductor and a controller configured or programmed to control the DAB converter using triple-phase-shift control. The controller can include a first proportional-integral controller to determine a parameter x based on comparison of a reference voltage and a measured voltage corresponding to either an HV voltage or an LV voltage; a voltage ratio calculator to determine a voltage ratio; a boundary calculator to calculate, based on the voltage ratio, a first boundary value corresponding to a boundary between low and medium power modes and a second boundary value corresponding to a boundary between the medium and high power modes; and a phase-shift-ratio calculator to determine phase shift ratios used in the triple-phase-shift control based on the parameter x, the voltage ratio, the first boundary value, and the second boundary value.
