Abstract
A method and computer program product for defining a PWM drive signal having a defined voltage potential. The PWM drive signal has a plurality of 'on' portions and a plurality of 'off' portions that define a first duty cycle for regulating, at least in part, a flow rate of a pump assembly. At least a portion of the “on” portions of the PWM drive signal are pulse width modulated to define a second duty cycle for the at least a portion of the “on” portions of the PWM drive signal. The second duty cycle regulates, at least in part, the percentage of the defined voltage potential applied to the pump assembly.
