Disclosed embodiments are directed to a technique to remove DC offset from current measurement signals through shunt resistors in digital signal processing for current reconstruction when using discontinuous pulse width modulation (DPWM). Such measurements regarding current are pertinent to a feedback loop used for a system including a DC-link capacitor, inverter, and motor. A method of removing DC offset comprises: determining a three-phase output current signal of an inverter, wherein the inverter is coupled to a motor and a power supply; producing a voltage signal based on the three-phase output current signal and the resistances of one or more shunt resistors disposed in the inverter; applying an analog gain circuit to the voltage signal; processing the voltage signal with an analog-to-digital converter (ADC); applying a DC offset corrector to the voltage signal; and performing current reconstruction on the voltage signal to produce a continuous current signal.
