All components on inverter board should follow below rules:
1. Component using conditions (component stress) must be within component specification including voltage
rating, current rating, temperature etc.
2. Component temperature should follow below:
T ∆T <=30 degree C, at 25, 35 degree C.
T Component temperature should be less than 70 degree C inside system at 35 degree C.
