I was working on electrical panels and drives for industrial refrigerators. I monitor the implementation of projects and work to improve the performance of the circuits to reduce the losses. Receive the requirements of clients from the sales department, calculate the parameters, and design the panels for achieving the best performance for industrial refrigerators and industrial coolrooms.

I was a Maintenance Engineer and Instructor of laser and CNC machines. In this factory, there were high power machines that they need to be monitored. I always try to make a balance to use the electricity for the cost reasonable. Sometimes I used the diesel generator to provide electricity.

It was interesting to saw the range of transformers. Some of them were huge. I worked on testing the transformers. Find the problem of them by using the results and try to solve them. For testing the transformers ‘oil I used Tan Delta and Gas chromatography devices. In this case, I Learned about transformers' fault. I have got some skills for different tests for transformers’ oil. Key Achievements: Testing more than 20 LV and HV transformers. Working with Gas chromatography device to analyse the transformers’ oil to detect an arc or short circuit in the winding. Working with the Tan Delta device to find the oil resistance. Measuring the humid in oil to make sure of the standard rate of that in oil.

In the research project implementation, I have worked on the invertors and find the new topology for inverters in wireless power transfer which has better performance compares to others. This thesis presents a new resonant converter made of two multiphase converters. The switches of this converter are switched somehow that solve the most important problem of multiphase inverters, namely the unbalanced current in the non-zero phase shift. This structure has a balanced current in all conditions. The structure is simulated by MATLAB software and it shows the correct operation of the proposed structure.
