Abstract :
The design and performance of a 30-kVA 400-Hz transistor inverter which furnishes all loads, except propulsion power, on a small advanced urban transit vehicle, a people mover, is described in this second half 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 power circuit is described in Part I, and the design and performance of the inverter control is discussed in Part II.
