This paper proposes, a single phase direct matrix converter using Insulated gate bipolar transistors, where undesired harmonics are minimized using three modulation techniques, namely: Sinusoidal Pulse Width Modulation, Delta Modulation and Adaptive Delta Modulation (ADM). This converter not only works as a Cyclo-Inverter (CI) but also as a Cyclo-Converter (CC). For these modulation techniques, a...
The laboratory prototype of a frequency converter (FC) is analyzed using readily available Spartan-3E Field Programmable Gate Array (FPGA) kit and Personnel Computer (PC). The output frequency range has been varied over a wide range by implementing Sinusoidal pulse width modulation (SPWM) technique, in order to minimize the harmonics, using very high speed integrated circuit hardware descriptive language...
A single phase matrix converter has been used as a Generalized single phase Power electronics converter such as Rectifier, Chopper, Inverter, AC voltage controller and Frequency changer using a single topology. An algorithm is developed that provides flexibility to single phase matrix converter (SPMC) to perform function of above various converters. Sinusoidal pulse width modulation (SPWM), multiple...
