Hybrid Voltage Vector Preselection-Based Model Predictive Control for Two-Level Voltage Source Inverters to Reduce the Common-Mode Voltage

IEEE transactions on industrial electronics (1982. Print), 2020
To suppress the common-mode voltage (CMV) and reduce the current total harmonic distortions (THDs) and ripples of two-level voltage source inverters (2L-VSIs), a hybrid voltage vector (VV) preselection-based model predictive control (MPC) strategy is ...

Common-Mode Voltage Attenuation of an Active Common-Mode Filter in a Motor Drive System Fed by a PWM Inverter

IEEE Transactions on Industry Applications, 2017
In previous work, the authors proposed an active common-mode filter (ACF) that is able to reduce the radiated noise from power cables connected to power converters and evaluated its radiated noise reduction effect by using an oscillator as a common-mode (CM) noise source. In this paper, this ACF is applied to a motor drive system fed by a PWM inverter,

Common mode stability in fully differential voltage feedback CMOS amplifiers

10th IEEE International Conference on Electronics, Circuits and Systems, 2003. ICECS 2003. Proceedings of the 2003, 2004
In this study consideration is made of the common mode (CM) behavior of two-stage fully differential amplifiers in voltage feedback (FB) connection. In particular, the interaction between internal CMFB circuitry and the external feedback network is investigated in order to highlight a possible operating point instability condition, due to the presence ...

A low voltage differential op amp with novel common mode feedback

1998 IEEE International Conference on Electronics, Circuits and Systems. Surfing the Waves of Science and Technology (Cat. No.98EX196), 2002
A new low voltage differential amplifier featuring a novel common mode feedback structure (CMFB) is presented. It provides rail-to-rail common and differential mode input range by the use of a nMOS depletion input pair transistors that can easily be processed in standard CMOS technologies.

Common-mode rejection ratio and the ‘Early-intercept’ voltage

International Journal of Electronics, 1977
The improvement in low frequency common-mode rejection that results from the replacement of the tail resistor of a simple BJT differential amplifier by a current source is shown to be related to a recently discussed parameter—the ‘ Early-intercept ’ voltage.

Common mode voltage reduction in a flying capacitor inverter

2010 1st Power Electronic & Drive Systems & Technologies Conference (PEDSTC), 2010
This paper investigates the common mode voltage in multilevel DTC drives and proposes a new algorithm for multilevel flying capacitor drives to reduce its common mode voltage. The new algorithm uses only those voltage space vectors which lead to lower common mode voltage.

Common mode voltage in a motor drive system with PFC

Proceedings of 14th International Power Electronics and Motion Control Conference EPE-PEMC 2010, 2010
Common mode voltage generated by a power converter in combination with parasitic capacitive couplings is a potential source of shaft voltage in an AC motor drive system. In this paper, a three-phase motor drive system supplied with a single-phase AC-DC diode rectifier is investigated in order to reduce shaft voltage in a three-phase AC motor drive ...
