Abstract :
A brief description of the WABCO/Reliance-pulse-width modulation (PWM) propulsion system and its potential operational advantages are presented. PWM system performance and early operating experience on Cleveland Transit System (CTS) car no. 154 are reviewed. CTS no. 154 is a modern ``airporter´´ car that has been retrofitted with engineering prototype inverter and control packages. It is running on the transit system to evaluate propulsion system performance and reliability. This car and the earlier breadboard experimental car, CTS no. 169, are the only known transit vehicles using ac induction motors.
