    摘要: Apparatus and methods for providing a voltage signal indicative of the voltage being supplied by each phase of a multiphase voltage being supplied to a load. For each phase, a phase to neutral voltage is produced by providing a virtual ground. For each phase, a phase to phase voltage is produced by determining a difference between a pair of phase to neutral voltages. Either the phase to neutral voltages or the phase to phase voltages for each phase are output depending on the configuration of the multiphase voltage being supplied to the load.
