High voltage buck converter topology for common mode voltage reduction

APEC '98 Thirteenth Annual Applied Power Electronics Conference and Exposition, 2002
A new DC buck power converter topology to actively reduce common mode voltage applied to the load is presented in this paper. The supply is designed to interface universal input DC-DC power supplies to a rectified 480 VAC (700 VDC) bus. By minimizing the common mode voltage produced, the size and cost of the passive filter elements can be significantly

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.

Common-mode voltage reduction PWM algorithm for AC drives

2009 IEEE Energy Conversion Congress and Exposition, 2009
The impact of common-mode voltage (CMV) generated by pulsewidth modulation (PWM) ac drives on motor bearings is well known. Several algorithms for CMV reduction have been proposed in the literature. While a few algorithms assume ideal switching and fall apart when nonidealities like inverter dead time are considered, some others are effective only in a

Common mode voltage in DTC drives using matrix converters

2008 15th IEEE International Conference on Electronics, Circuits and Systems, 2008
The paper analyzes the common mode voltage at the output of matrix converters. Based on the theoretical analysis, an approach to reduce the common mode voltage for direct torque control drives using matrix converter is then proposed. The proposed method can be easily implemented without increasing computational requirements and it has been shown to ...

Design of Passive Common-Mode Attenuation Methods for Inverter-Fed Induction Motor Drive With Reduced Common-Mode Voltage PWM Technique

IEEE transactions on power electronics, 2020
This paper investigates the influence of active zero vector pulsewidth modulation (AZPWM-1) and space vector pulsewidth modulation (SVPWM) on the design of passive common-mode (CM) attenuation methods to reduce CM current and shaft voltage in inverter ...

Reduction of Interference Due to Common Mode Voltage in Biopotential Amplifiers

IEEE Transactions on Biomedical Engineering, 1983
We review how the nonideal properties of biopotential amplifiers can transform common mode voltage into interference. We then review several design approaches for two-and three-electrode amplifiers, both nonisolated and isolated, that reduce this interference.

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 ...

Control of high common mode voltage during transthoracic defibrillation

IEEE Transactions on Biomedical Engineering, 1995
A high common mode voltage (Vcm) relative to earth ground is produced on the myocardium during the delivery of a defibrillator pulse and can generate a differential error signal when potential gradients are recorded with bipolar electrodes and isolation amplifiers.

Common-Mode Voltage Elimination for Dual Two-Level Inverter-Fed Asymmetrical Six-Phase PMSM

IEEE transactions on power electronics, 2020
The voltage-source inverter with pulsewidth modulation (PWM) is widely used in motor drive applications owing to the technical maturity and simplicity. However, the inverter operating in the discrete and impulse state generates the high-frequency common ...
