In this paper a matrix converter with a special circuit is presented. It works so that no overvoltage can be produced by an interruption of an input phase when operating with inductive load current. Also a switching off of one or more semiconductors of the inverter matrix can not produce the high voltage spikes by using the overvoltage protection circuit. This matrix converter works without any complicated...
This work presents improved sinusoidal pulse width modulation (ISPWM) used for reduction of harmonics from the output of cycloconverter based on single-phase matrix converter (SPMC). The usage of inductive load often arise the problem of switching spikes which can be overcome by providing a commutation path for energy stored at the load. The insulated gate bipolar transistor (IGBT) was used as the...
This paper is concerned on FPGA design for control implementations of the Single-Phase Matrix Converter (SPMC) operating as a single-phase Inverter. The Sinusoidal Pulse Width Modulation (SPWM) technique is used to synthesize the output voltage with. The power circuit uses the Insulated Gate Bipolar Transistor (IGBT) as switching device in the SPMC implementation. Safe-commutation strategy was incorporated...
