The synchronous machine and excitation system is illustrated in Figure 1.  In this system, the voltage regulator has two parts; a control algorithm to determine the field current of the brushless exciter, and a power converter which achieves this command.  The brushless exciter machine rotor voltage is rectified – which in turn supplies the field current to the synchronous machine.
