要約(英語): This study proposes a novel current detection technique to reduce the current noise in a PWM inverter with a current sensor in series with low-side switches at high modulation index. In the proposed technique, the modulation of the high-side switch is applied to the voltage reference phase with maximum value and the current detection technique compensates currents in the voltage reference phase with medium and minimum values with the current in the voltage reference phase with maximum value. Experimental results demonstrate that the proposed technique can reduce the noise of q-axis currents.
