    Does a 3-phase phase-locked loop diagram possible for an AC to DC battery charger?

    Hi there, In order to achieve unity power factor control, the phase of the AC voltage needs to be obtained. The phase is obtained through a phase-locked loop (PLL). Take a look for single phase control structure of the PLL , Another might be understandable For such similar way I want...
