Reduction of common mode voltage using multilevel inverter

2016 International Conference on Energy Efficient Technologies for Sustainability (ICEETS), 2016
In this paper, a direction to reduce common-mode voltage (CMV) at the output of multilevel inverters (MLI) using a sinusoidal pulse width modulation (SPWM) technique is discuss. As SPWM technique does not require computations therefore, it is easy to implement in digital controllers. This paper makes the simulation implementation of a SPWM technique to

Common-Mode Noise Reduction in Phase-Shifted Full-Bridge Converter by Common-Mode Voltage Cancellation

2020 IEEE 9th International Power Electronics and Motion Control Conference (IPEMC2020-ECCE Asia), 2020
Full-bridge (FB) converter is a widely adopted topology in medium-to-high power conversion applications, and soft switching can be realized with phase-shifted control to achieve high efficiency. As the diagonal switches turns on (off) at different time, the displacement current flowing through associated parasitic capacitances (including the ...

Simultaneous Common-Mode Voltage Reduction and Neutral-Point Voltage Balance Scheme for the Quasi-Z-Source Three-Level T-Type Inverter

IEEE transactions on industrial electronics (1982. Print), 2020
The conventional three-level inverter only has voltage buck capability. The quasi-Z-source three-level T-type inverter (QZS 3LT$^2$ I) has been proposed to realize voltage buck–boost operation.

Test buffer with extended common mode input voltage

Melecon 2010 - 2010 15th IEEE Mediterranean Electrotechnical Conference, 2010
The paper presents an adequate buffer for testing integrated circuits. The buffer operation is based on changing the DC level of the incoming signal to a reference common mode voltage REF V with an error of 0.003% for a large domain of common mode input voltages.

Double Vector Model Predictive Control to Reduce Common-Mode Voltage Without Weighting Factors for Three-Level Inverters

IEEE transactions on industrial electronics (1982. Print), 2020
The conventional model predictive control (MPC) suffers from high common-mode voltage (CMV) magnitude and large current ripples. In this article, the reduced CMV MPC strategy with double vector (RCMV-MPCDV) is proposed for three-level inverters, which ...

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 ...

An approach to reduce common-mode voltage in matrix converter

IEEE Transactions on Industry Applications, 2003
In this paper, an approach to reduce common-mode voltage at the output of a matrix converter is discussed. A new modulation strategy which reduces the common-mode voltage at the output is presented. The proposed method maintains the active voltage vector and distributes zero vector equally within a sampling period and reduces square RMS of ripple ...
