Advanced drive systems

Advanced drive systems are DC to 3 phase AC conversion systems and consist of all components necessary to supply a load with electrical energy in the requested quality and quantity [Stengert, K et al., 197] [Tursky, W, 2001]. The integration technology for advanced drive systems is shown for systems with DC voltages from 30 V to 900 V and power levels from 15 kW to 250 kW. The main functional blocks of the presented advanced drive systems are: power semiconductor switches in three phase inverter configuration, DC link with the storage capacitors, sensors for current, temperature and voltage, gate driver hardware for the switches, controller hardware, bus interface, power supply for the electronics, common housing for the whole system and cooling [Backhaus, K, 1999]. Due to its proven high reliability, SKiiP-technology has been chosen for the mechanical construction. New solutions for the layout of bus bars and DC link are demonstrated which allow ultra low inductance. A parasitic inductance of
