Description
This project presents the hardware implementation of the single phase in seven level multilevel inverter using the Cascaded HBridge using Separated DC sources. The main objective of is to increases the number of levels with a lower number of switches at the output without adding any complexity to the power circuit. The main advantages of the proposed method are to reduce the Total Harmonic Distortion, lower order harmonics and electromagnetic interference and to get high output voltage. To minimize the total harmonic distortion equal area criteria (EAC) switching technique is presented and it can enhance the output voltages from proposed work. The Inverter is operated by using Arduino controller which generates PWM pulses. The use of Arduino makes the process of using electronics in multidisciplinary projects more accessible. It is well suited for processing control parameters such as speed of an Induction Motor.
HIGHLIGHTS
An experimental investigation has been carried out on single-phase multilevel inverter to obtain 7-level output voltage using cascaded four H-bridge units.
The proposed system consists of four cascaded H-bridge MOSFET-based voltage source inverters, a microcontroller-based Arduino module, four separate input dc sources and isolating circuit. The gate drive signals for MOSFETs of the four H-bridge inverters are generated by using -based Arduino board.
The arduino has been used to reduce the complexity of generating gate drive signals for higher levels of inverter output voltage. Different-level output voltages have been obtained from experimental works.
It is found that the proposed system requires less number of power switching devices and total harmonic distortion is reduced with increasing number of levels at the output voltage of the multilevel inverter.

Well i got the ARDUINO BASED UNDERGROUND CABLE FAULT DETECTION project and i was surprised to see it delivered in such a good condition. I was afraid that sending a delicate circuit in through international shipping may damage it, but their packaging is extremely good.
