KIEPE Traction Control KTC

Fast torque control in every operating situation.
Improved efficiency by using synchronous pulse patterns in the upper speed range. This increases the overall efficiency of the traction machine and traction converter.
Optimized wheel slide and slip protection.
Reduction of noise and energy consumption with optimized machine flux control.
Reduction of acoustic resonances in drivetrain and in braking resistor by optimized switching frequency modulation.
Optimized driving characteristics in condition of icy overhead line.
Reliable and stable start on very high inclines.
Highest priority on electrical braking capability, even in case of the overhead line voltage failure.
High recuperation level and protection against consumption of the external energy.
Controlled acceleration and deceleration at different loads and road profiles.
Traction operation on 24V-DC-link voltage for low speed and rescue drive mode.

Active damping of torsional oscillations in a drivetrain of electric buses (Patent pending)
Very dynamic electronic ASR (inside of inverter control)
Variable switching frequency (frequency band modulation)
Reduction of subjective and objective acoustic noise perception
Optimized system noise
Special control algorithm for acceleration at very high inclines (up to 22 %)
HighPriority on electrical Brake capability (until zero speed)
Overmodulation with synchronous pulses (+15 % machine voltage), lower energy
Energy optimized drive mode (optimal machine flux at lower torque)
Acceleration Control
