Power electronic converters, especially DC/AC inverters have been extending their range of use in the industry because of their numerous advantages. They typically the staircase voltage waveform (from several dc sources) which has reduced harmonic content. This project aims to extend the knowledge about the performance of five levels of Cascaded H-Bridge multilevel inverter topology with Arduino. The PWM pulse will be generated by using Arduino Uno R3. The output voltage is the sum of the voltage that is generated by each bridge. The switching angles can be chosen in such a way that the total harmonic distortion is minimized.
Cascaded H-Bridge multilevel inverter topology
The cascaded H-bride multilevel inverter is to uses capacitors and switches and requires fewer components at each level. This topology consists of a series of power conversion cells and power can be easily scaled. The combination of capacitors and switches pair is called an H-bridge and gives the separate input DC voltage for each H-bridge.
