1. A charging system, comprising:

  • a battery;

    a three-phase stator winding having a plurality of output connections;

    a field winding magnetically coupled to the stator winding;

    a controller; and

    a half-wave controlled rectifier bridge coupled between the output connections of the stator winding and the battery, wherein the half-wave controlled rectifier bridge includes a plurality of controllable rectifying elements coupled to a plurality of non-controllable rectifying elements at respective terminal nodes (A, B, C), the respective terminal nodes being coupled to the output connections of the stator winding, one of the terminal nodes being connected to the controller by a voltage sense line, and wherein the controller senses a plurality of edges on the voltage sense line for determining commutation timing of the controllable rectifying elements.
