Controlling active load, e.g. induction motor, relief network for current converter(s) involves influencing load relief network drive time point or duration of depending on operating conditions of current converter

摘要

The method involves influencing the drive of the load relief network depending on the operating conditions of the current converter by influencing the drive time point or duration. The network is only driven if the electric current in the current converter to be switched exceeds a defined threshold dependent on the converter's operating conditions, e.g. on the load current.
