Abstract
Multiphase trans-inductor voltage regulator fault diagnostic. One example is a method of detecting electrical faults in a multiphase power converter, the method comprising: driving, by a controller of the multiphase power converter, a first phase of the power converter, the first phase comprising a phase-one transformer module; driving, by the controller, a second phase of the power converter, the second phase comprising a phase-two transformer module distinct from the phase-one transformer module; testing, by the controller of the multiphase power converter, for a phase-one electrical fault associated with the phase-one transformer module; testing, by the controller, for a phase-two electrical fault associated with the phase-two transformer module; and driving, by the controller, a fault indicator in the presence of a phase-one or phase-two electrical fault.
