ABSTRACT:
The regulation range of a conventional bang-bang current regulator is extended by altering the current command or feedback signals to cause the feedback signal to exceed the command signal sooner in time than it otherwise would and fall below the command signal later in time than it otherwise would. For relatively low command signal values, the current is regulated in a discontinuous series of reduced peak excursion pulses, enabling the average value of current to be regulated down to a lower value than possible without the alteration.
