HV-500 TECHNICAL DESCRIPTION
CURRENT LIMIT
REDUCTION
Maximum stepless AC current
limit depending on the IGBT
temperature in order to protect
them from damage.
POWER LOSS
The dissipated power depends on:
•
PWM switching frequency
•
AC frequency (motor rotation frequency)
•
AC current
•
AC voltage
•
DC voltage
With a calculated example we demonstrate the power loss of the inverter. Power loss can be seen
compared to AC current.
Power loss calculated with the following inputs:
DC voltage:
Motor KV:
PWM switching frequency:
