I need to design a low cost power analyzer for my thesis work (solar inverter system) as one is not available and their is no plan to buy a new one.
Power Analyzer will only be used as an instrument for measuring electrical signal of characteristics 230VAC; 0.5-10 Amps. current; Single Phase and frequency 50Hz.
I have access to Infineon Relax Kit (in my possession) and/or ATSAM4CMS Demo Board (planned) and plan to use on chip ADC. Available ADC : 12 bits-4M Samples in Infineon XMC4500 and 20-bit Sigma Delta Converter 16kS/s.
I need some advice/guidance regarding :
List of all measurement that will be take :
Any other economical development board recommendation may be considered if the above mentioned board are not adequate for mentioned operation.
Finally the power analyzer will be connected to Laptop/PC to display all relevant reading on screen. Complex mathematical operations could be dome on PC is required.

I need some advice/guidance regarding :
- How to find out Total Harmonic Distortion (low order; up to 20th order)
- How to find Power Factor Corruption
- How to find fundamental frequency of a signal
List of all measurement that will be take :
- IRMS
- IPEAK
- VRMS
- VPEAK
- PAVG
- Power
- Energy
- Frequency
- THD
- PFC
