This Paper introduces new hybrid converter topologies which can supply simultaneously AC as well as DC from a single DC source. The new Hybrid Converter is derived from the single switch controlled Boost converter by replacing the controlled switch with voltage source inverter (VSI). This new hybrid converter has the advantages like reduced number of switches as compared with conventional desig...

This paper explores the advantages and implementation of Digital Signal Processing (DSP) TMS 320F2812 to generate gate pulses. The main features of this DSP are elaborated. The technique to obtain gate pulses in different pulse width modulation methods in order to control three-phase voltage source inverter is explained systematically. The steps needed to develop the program are highlighted in ...

This paper presents the performance of the extended Kalman filter (EKF) for speed sensorless indirect field oriented control (IFOC) of a squirrel cage induction motor (IM) supplied by a pulse width modulated (PWM) voltage-source inverter. The rotor speed of the induction motor is estimated, according to this method, using the direct measurements of the stator voltages and currents without the s...

This paper presents the comparative study of various Multicarrier Pulse Width Modulation techniques with Sinusoidal reference for single phase seven level cascaded Z-source inverter designed with three intermediate Z-source networks connected between the input source inverter circuit. The cascaded Z-source based MLI technique enhances the fundamental output voltage and reduces the Total Harmoni...
