Various sigma–delta ( $\Sigma$ notation="LaTeX">$\Delta$ ) modulation techniques for reducing the maximum peak-to-peak amplitude of common-mode voltage (CMV) by 80% in a five-phase, high-frequency source inve...

<div class="keywords">Space vector pulse width modulation (SVPWM) is a popular technique in the field of variable frequency induction motor drives. It gives better working and good direct current bus utilization comparison to sinusoidal PWM (SPWM) method. However, it decreases harmonic fluctuations generates high common mode voltage (CMV) fluctuations, which results currents inside motor....

This article proposes and studies different sigma–delta ( $\Sigma$ notation="LaTeX">$\Delta$ ) modulation strategies for obtaining a constant common-mode voltage (CMV) by eliminating the CMV level transitions...

A high-speed and high-accuracy continuous-time common-mode feedback block (CMFB) is presented. To satisfy speed and accuracy requirements, some modi ̄cations have been applied on di®erential di®erence ampli ̄er (DDA) CMFB circuit. The proposed method is applied to a folded cascode op-amp with power supply of 3.3V. In order to verify the proposed circuit, simulations are done in 0.35 m standard CM...
