Diseño e implementación de un inversor multinivel monofásico por fijación de diodos con optimización armónica

Abstract

This paper grade analysis, design and implementation of a multilevel inverter locked diode

with a maximum of five levels we were performed. The topology of the inverter is

determined taking these gray areas, modulation (PWM) applicable to the setting of diodes,

which also provides optimization of harmonics and inverter stages were designed was

selected. This technique is trained on a Digital Signal Controller (FPGA) which generates

the signal for controlling said inverter. Simulations modulation multilevel inverter set by

diodes were performed in Matlab and the PCB design in Eagle. The tests were carried out

with resistive load as a result of this prototype will be built and finally validate the results.

In multilevel investors you can find various topologies, such as the basic half-bridge, full

bridge and other more complex with cascading bridges “H”. The use of these elements is of

vital importance in the industry , fulfilling functions in case of power supplies ( UPS ' S ,

welders, cutters , induction furnaces , switch mode voltage) drivers and engines (activation

of robots, air conditioning, elevators , AC servos ) that cause harmonic distortion in the

signal quality decreasing energy caused disruptions in electrical service [1] .

Recently, multilevel converters have emerged as a competitive option for power conversion

halved in the high - power range, especially from the economic point of view, which today

is one of the factors that weighed when making a project [1].
