Abstract
A dual alternator system includes a main alternator controlled by an electronic voltage regulator, a secondary alternator system having a secondary alternator controlled by a LIN controlled alternator voltage regulator and an electronic control unit (“ECU”) coupled to the LIN controller alternator voltage regulator by a LIN bus that that determines whether the secondary alternator should be off or operated to generate current. The ECU when it determines that the secondary alternator should be off sends a voltage setpoint signal to the LIN controlled alternator voltage regulator having a low value that is well below nominal system voltage. The ECU when it determines that the secondary alternator should be operated to provide current sends a voltage setpoint to the LIN controlled alternator voltage regulator having a high value that is well above a nominal system voltage and a MECL setpoint value.
