| Abstract |
This paper describes the electric drive system of the hybrid vehicle developed in Italy by Alfa Romeo and Ansaldo, financed by the Natjonal Council of Research (CNR). The hybrid vehicle electric powerplant consists of an induction motor, a transistor inverter and a 96 Volt Ni-Cd battery pack. The propulsion electric motor is a special purpose three-phase asynchronous machine. With forced air cooling it produces 6 Kw continuously and 12 Kw overload. The inverter utilizes high speed power darlington transistors to pulse the battery voltage and obtain a PWM waveshape. The electric power plant includes a microprocessor system dedicated to determine the available capacity of the Ni-Ci batteries. The system design, with particular consideration for the transistor inverter, and the results of some experimental testes are described. |
