Then, according to the mathematical mode of the MMC half-bridge sub-module, the analytical formula of the bridge arm power after the common mode voltage is injected is derived. From the perspective of reducing the power fluctuation of the bridge arm, a circulation current injection strategy is ...
As you correctly stated the input common-mode voltage range of INA321 is from (V-)+0.35V up to (V+)-1.2V, thus for Vs=2.8V supply it means Vcm_max=1.6V; however, the upper and lower limit of the input range are bounded by the output swing of amplifier A1, and fo...

2. Low Common-Mode SVPWM Method 2.1. Classification of Basic Vectors The inverter using SVPWM is a three-phase power supply, and the sum of its three phase voltages may not necessarily be equal to zero. The arithmetic mean of the three phase voltages is defined as the common-mode voltage....
For the multiphase motor drive system, current harmonic components in stator windings and the common-mode voltage are the main factors affecting the control performance. In this paper, a novel model predictive torque control (MPTC) considering both harmonic and common-mode voltage suppression is prop...
voltages. But the common mode gain Ac magnifies the common mode DC voltage between the two inputs. The ratio of two gains is said to be as a common mode rejection ratio. The value of the format is in dB. The formula of a common mode rejection ratio is calculated by the following ...
