Abstract

See full text

Systems and methods for mitigation of resistor nonlinearity errors in a power converter are provided. In at least one embodiment, the power converter comprises at least one power switch coupled to an input voltage, a pulse width modulation (PWM) circuit for generating control pulses for the at least one power switch, at least one output inductor coupled to a respective one of the at least one power switches, a current sensor coupled in parallel with the at least one output inductor, and at least one circuit element. The current sensor comprises at least one capacitor, at least one resistor for each of the at least one output inductors, and is coupled to the PWM circuit at a current bleed node. The at least one circuit element is coupled to the current bleed node and bleeds a bleed current from the current bleed node when a power switch is turned on.
