Modular inverter system
T6 APD
Electrify auxiliary systems in vehicles with the T6 APD inverter system from KEB Automation. The T6 APD is designed for electric vehicles running on batteries or hybrid applications, and meets all requirements placed on electronic components or systems in relation to mechanical and thermal properties, ambient conditions, EMC, safety or service life.
The scalable and modular T6 APD system can be flexibly adapted to different vehicle requirements, and enables the integration of up to six inverter modules available in three different performance levels with rated output currents of 16.5 A, 33 A and 60 A. The T6 APD reliably handles dynamic and energy-efficient speed and torque control tasks.
The integrated mobile control system (MCU) offers the possibility of developing new automation solutions for electric vehicles and mobile machines. A communication gateway for higher-level vehicle control is available in the form of J1939 CAN and UDS APP. DC EMC filters, integrated as standard, also ensure a high degree of operational reliability in combination with other high-voltage components in the vehicles.

SAFETY AND SECURITY
Our development phases depend on ASIL and SIL. Operational safety and cyber security use similar development processes. Here, the focus is on identifying and assessing the hazards and risks that can arise from the intended functions. Cyber security is a multi-dimensional concept that covers the entire technical life cycle and the whole organisation of a company. As regulation UN R155 is relevant to the type approval (homologation) of electric vehicles, it primarily concerns vehicle manufacturers. However, suppliers must also be able to demonstrate the cyber security of their products, internal processes and services.
