Common-mode voltages (CMVs) can lead to premature failure of the motor insulation system in medium-voltage (MV) current source inverter (CSI)-fed drives. A series of nonzero-state modulation (NZSM) techniques are proposed for the CMV reduction. In these methods, the zero states are avoided...
When the conventional space vector PWM (SVPWM) schemes are applied to regenerative AC drives, very high neutral to ground voltages are generated at the motor. This can result in premature failure of the motor bearings and stator winding insulation to ground. The DC bus to ground voltage may ...
92,93: for each participant, voltages at each electrode and time point (downsampled to 250 Hz) as dependent variables were regressed (using MATLAB’s regress function which implements least squares regression) against trial parameters and an intercept term as independent variables to obtain ...

"Always know what you are working on and not only verify if there is power on the circuit, but what the voltages actually are," said an electrician who works on a rolled sheet metal galvanizing line. "Always make sure it is dead and locked off. ALWAYS!" said a third-year apprenti...
Cav1.3 channels activate at more negative voltages enabling them to modulate neuronal firing behavior and to serve pacemaker function in neurons8,9, which plays an important role in neuronal signaling and suggests that pharmacological modulation would also affect brain function to some extent. Therefore...

The molecular mechanisms of progressive right heart failure are incompletely understood. In this study, we systematically examined transcriptomic changes occurring over months in isolated cardiomyocytes or whole heart tissues from failing right and left
Tail currents measured at positive voltages suggested that channel open probability decreased after long hyperpolarizing pulses (Fig. 2f). However, due to the extremely long voltage pulses in these experiments, and their effect on the distribution of chloride ion, we are unable to draw any firm ...
