Application 2
Silicon rectifier and hybrid 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.
Correct wiring:
DC
power
reactor
reactor
AC motor drive
motor
silicon rectifier
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 hybrid drive due to higher rectifier temperature.
Correct wiring
large-capacity
power
reactor
small-capacity
AC motor drive
