Abstract :
The design and performance of a people mover¿a 30- kVA 400-Hz transistor inverter which furnishes all loads, except propulsion power, on a small advanced urban transit vehicle¿is described in this first installment of a two part sequence of papers. With a nominal 750-V dc input, the inverter supplies 30 kVA at 0.8-lagging power factor, 200-V line-to-line root mean square (rms), and three- phase 400-Hz output. The design and performance of the power circuit is described in Part I, and the design and performance of the control is covered in Part II.
