Application 2
Silicon rectifier and AC motor drive are connected to the same power.
Problem: Switching spikes will be generated when the silicon rectifier switches ON/OFF.
These spikes may damage the mains circuit.

Application 3
When the power supply capacity exceeds 10 times of the inverter capacity.
Problem: When the mains power capacity is too large, line impedance will be small and the
charge current will be too high. This may damage AC motor drive due to higher
rectifier temperature.
