    Noise in CY8CKIT-050 PSoC® 5LP Development Kit board

       Hi I have the CY8CKIT-050 PSoC® 5LP Development Kit board. With this board I send the PWM signals to switch the Mosfets  in a inverter. The inverter is the source for a three phasic induction motor. The PWM signals are isolated with optocouplers from the psoc board to the Mosfets drivers. When the input voltage of the inverter is 110v, the PSoC stops the modulation, so the inverter is in short circuit. With a scope I see noise in the 5V and 3.3V pins of the board. This noise can reboot the PSoC? or the circuit protection of the board are turning off the digital pins of the board?
