In this paper a single-inductor dual-output (SIDO) buck-boost PFC converter operating in critical conduction mode (CRM) is proposed. By multiplexing a single inductor, each output of SIDO buck-boost converter can be regulated independently. Compared with conventional two-stage multiple output converter, SIDO buck-boost PFC converter benefits from significant overall cost saving, small size and ...

The most popular and best modulation method used among Pulse Width Modulation (PWM) technique is Space Vector Modulation (SVM) method. SVM generates low Total Harmonic Distortion (THD) and it is well suitable for motor control. Harmonics is one of the major power quality issues occurring in most of the application. SVM holds the major advantage that only one switch is turned on at a time. The p...

In this paper, we present a comparative assessment of Space Vector Pulse Width Modulation (SVPWM) and Model Predictive Control (MPC) for two-level three phase (2L-3P) Voltage Source Inverter (VSI). VSI with associated system is subjected to both control techniques and the results are compared. Matlab/Simulink was used to model, simulate and validate the control schemes. Findings of this study s...

The Diode Clamped Multilevel Inverter (DCMLI) is an attractive type multilevel inverter due to its robustness. This paper discusses new modulation strategies for a single phase five level H-bridge type DCMLI with reduced components as compared to conventional DCMLI. The chosen multi level inverter is controlled with multicarrier based Sinusoidal Pulse Width Modulation (SPWM) technique with Vari...

In this paper comparison of Selective Harmonic Elimination (SHE) method with different Pulse Width Modulation (PWM) technique which are used as gate pulse for firing the IGBT‟s. Higher order harmonics are easily eliminated by selecting a proper tuned value filters but lower order harmonics such as 3rd, 5th, 7th, and 9th are not easily eliminated. This paper includes NewtonRapson method with ran...

Multilevel inverters have drawn tremendous interest in high power and high voltage application. Multilevel inverters have unique structure which makes it possible to reach high voltages with less harmonic content. The harmonic content of the output voltage waveform decreases as the number of output voltage increases. The main advantages are lower Total Harmonic Distortion (THD), less stress on ...

This paper analyses the transient behaviour of SwItched-current (SI) memory cells placed at the front-end of high-speed A/D interfaces. Based on the Volterra series method, the non-linear sampling process occurring in such cells is studied and closed-form expressions are obtained for the Total Harmonic Distortion (THD) and the intermodulation distortion. The analysis is extended to the case of ...
