Hi,
I'd like to build a 3-phase DC to AC inverter that can regulate its output around 230V and frequency 50Hz and can be connected to the grid. I'd like to hear from professional people what is the most powerful microcontroller that can be used ? I am using PIC micro and have been advised to use PIC18F2331 as it contains many PWM ch . What is your opinion and what kind of low cost solution to feedback the output voltage and current ??
I suggest to go for STM8 or STM32 Cortex M0 family. They have 3phase Motor Control PWM Timers and 12 bit ADC. I think best microcontrollers - low cost @ high performance.
