Analysis and Measurement of Non-Intrinsic Differential-Mode noise in a SiC inverter fed Drive and its Attenuation using a Passive Sinusoidal Output EMI Filter

Kumar, M.; Kalaiselvi, J. (2022-10-21)

The analysis, measurement, and attenuation of nonintrinsic differential-mode (NDM) and common-mode (CM) noise in an induction motor (IM) drive are discussed in this paper. In a voltage source inverter (VSI) fed drive, ...
Analysis of Common-Mode Noise and Mixed-Mode Differential-Mode Noise in Dual Active Bridge Converter

Dwiza, B.; Kalaiselvi, J.; Gorla, N.B.Y.; Pou, J. (2022-10-21)

The dual active bridge (DAB) converter is one of the widely explored topologies in recent years due to its remarkable features, such as inherent soft-switching characteristics, galvanic isolation, and high power density. ...
Analytical approach for common mode EMI noise analysis in dual active bridge converter

Dwiza, B.; Kalaiselvi, J. (2021-06-20)

The increased demand for high power density converters resulted in increased EMI. This is addressed by considering all the converter parasitics along the noise propagation path. In this paper, the analytical approach for ...
Design and development of a single CM filter for bearing current and ground current reduction in a dual two level inverter fed open end winding induction motor drive

Kalaiselvi, J.; Srinivas, S. (2021-10-10)

A dual two-level inverter with an open-end winding induction motor can realise a three/four level voltage space vector. High switching frequency coupled with the use of such multilevel inversion system can produce good ...
Fault-tolerant and self-reliant characteristic in series resonant converter for semiconductor open/short circuit faults

Bhakar, P.S.; Kalaiselvi, J. (2022-07-22)

With the increased popularity of series resonant converter (SRC) in grids and microgrids, a robust converter with fault-tolerant feature becomes supremely important. A single switch primary side failure results in half of ...
Impact of PWM and duty ratio control on voltage for Sic Fed three phase BLDC motor drive

Dwivedi, D.; Singh, S.; Kalaiselvi, J. (2022-07-10)

This paper presents an analysis of phase voltage and dc bus utilization for a three-phase Brushless DC motor (BLDC). Both pulse-amplitude (PAM) and pulse-width modulation (PWM) is employed to control the phase voltage and ...
Self-reliant feature in DC-DC converters for open circuit faults

Bhakar, P. S.; Kalaiselvi, J. (2021-06-18)

With vast applications of dc-dc converters in grids and micro grids, the need of a vigorous converter with fault tolerant capability becomes very important. Dual active bridge (DAB) and series resonant converters (SRC) ...
A simple active gate driver circuit to reduce switching oscillations and overshoot

Nistane, T.J.; Singh, S.; Kalaiselvi, J. (2022-08-25)

SiC MOSFETs are gaining more attention due to their ability to operate at high voltage and high switching frequency with very low losses. However, due to fast switching, interaction of such high di/dt and dv/dt with the ...
