Abstract
Systems, methods and devices are described for controlling a vehicle electrical generator. A regulator for controlling a generator in response to an input signal received from a control module suitably includes a discriminator module, a processing module and a switching circuit. The discriminator determines whether the regulator is operating in voltage or torque control mode. If the input signal is a voltage control, the output generator produces a modulation signal to produce a desired voltage between two battery terminals. If the input signal is a torque control, the output generator produces one or more modulation signals (e.g. pulse width modulation signals) to control the torque of the generator. The modulation signals are applied across a field coil or other controllable element of the generator by a switching circuit that applies positive and/or negative voltage from the battery terminals as appropriate.
