edge aligned
Not sure if
Center-Aligned PWM = Symmetric PWM
Edge-Aligned PWM = Asymmetric PWM
If they're similar, then it has been shown that symmetric PWM signals generate fewer harmonics in the output currents and voltages.

HINDI, you're right. The speed of a motor depends greatly on the supply voltage. V = IR + kw. At no load, IR is negligible, so, V = kw, where w is angular velocity of the rotor.
My colleague constructed one 3-phase grid connected power inverter. However, when he tested the module in lab, the main switchboard was tripped. Is it because of synchronization problem? Thanks.
What are the design issues that I should pay attention when construct a Grid-Connected Power Inverter so that the inverter can be connected to power grid without problem? Thanks.
