A lug with relatively small resistance is provided that allows current to be determined between a source and a load by measuring the voltage drop across the lug. The voltage drop is sufficient to be above the electronic noise, and yet the resistance of the lug is low enough so that the heat produced by current flow is small compared with the heat generated by the source. The material comprising the lug is of a type and strength to be readily manufactured, and its resistivity varies by a relatively small amount with temperature.

A control for operating an electromagnetic machine in a starting mode of operation detects a magnitude of a parameter of power applied to an armature winding of the electromagnetic machine relative to a stationary frame of reference and converts the detected parameter magnitude into field and torque producing components relative to a rotating frame of reference. A power source coupled to the armature winding is controlled during operation in the starting mode such that a rotor of the machine is accelerated.

A digital voltage regulator for an electrical power system including a permanent magnet generator (PMG), an exciter, and a main generator. A controller multiplies the frequency of the generator output voltage by a predetermined value to provide a sampling signal having the multiplied frequency and synchronized with the generator output voltage. The controller also provides a sawtooth voltage signal having a repetition rate equal to the frequency of the sampling signal and an incrementing rate determined by the system clock signal. The generator output voltage is sampled at the frequency of the sampling signal. When the difference between the sampled signal and a reference voltage is greater than the sawtooth voltage, the PMG voltage is switched to provide voltage for the exciter field winding.
