This paper presents a comprehensive analysis of various bipolar Multicarrier Pulse Width Modulation (MCPWM) strategies with Sinusoidal reference for three phase Nine level Trinary Source cascaded inverter. A new approach of nine levels is for medium voltage applications. The proposed topology uses reduced number of switching devices and thus reducing losses and low THD in comparison with the co...

This paper dkcusses a higbfy stable, triple-integration noiseshaping technique and a precise differential pulse-width modulation (PWM) output method, which permits greater accuracy in monolithic audio D-to-A converters (DAC’S), without trimming. Based on these new techniques, using 1.5pm CMOS technology, a 17-bit 20-kHz bandwidth DAC LSI with d@d filters was successfully developed. An SNR (S/(N...

This paper presents the analysis for different control techniques in Z-source inverters. The voltage gain versus modulation index from simulation result is compared with the mathematical calculated voltage gain. Further detailed analysis of %THD, %harmonics of output voltage at different modulation indexes for different boosting techniques of a Z-source inverter are also performed with respect ...

The voltage and current THD values of the symmetric inverter operated by fundamental switching frequency are closer to the IEEE 519 standard. Some additional filter circuit is required to minimize the THD values within the specified limits. However symmetric multilevel inverter requires more number of components and driver circuits. Asymmetric multilevel inverter is proposed in this chapter to ...

BACKGROUND Infrequent dialysis, namely once-a-week session combined with very low-protein, low-phosphorus diet supplemented with ketoacids was reported as a useful treatment schedule for ESRD patients with markedly reduced residual renal function but preserved urine output. This study reports our findings from the application of a weekly dialysis schedule plus less severe protein restriction (s...

OBJECTIVE A less-invasive method has been developed that may provide an alternative to monitor cardiac output from arterial pressure: beat-to-beat values of cardiac output can be obtained by pressure recording analytical method (PRAM). The purpose of this study was to assess the reliability of cardiac output determination by PRAM in cardiac surgery. METHODS Cardiac output was measured in 28 p...
