Hi,
We are using ARM based LM3S817 microcontroller for Inverter. Can i do grid synchronization with this controller.
If any possibilities please provide some solutions and related documents as soon as possible.

Hi Radhika,
We do not have any specific example applications for grid synchronization with the Tiva C series, but the LM3S817 includes 6 ADC inputs that could be used to monitor the frequencies and phases of your generator and grid voltages. The input range for ADC pins on the LM3S817 is -0.3 to VDD +0.3V so you would need supporting components to sample higher voltages. You could then use a GPIO to control a relay which closes the generator circuit breaker when the generator and grid circuits are in phase. For more information please consult the ADC section in the datasheet.

Hi,
Thank you for your information. But u mentioned "GPIO has to be used to control a relay which closes the generator circuit breaker when the generator and grid circuits are in phase". Could u explain in detail and provide sample code to do this mechanism. And is there any possibility to occure delay's while synchronizing generated output and grid output.
