ENERGY DEMAND AND CONSUMPTION REQUIREMENTS FOR SOLID-STATE CONTROLLED LINEAR INDUCTION MOTOR PROPULSION SYSTEMS

The electrical energy demand and consumption requirements of the tracked levitated, linear induction motor propelled, vehicle are presented. Energy requirements for the various modes of acceleration, cruise, and deceleration are established. It is shown that the implementation of the various techniques of solid-state power control (power conditioning) has significant impact on the electrical energy requirements. The real and complex power requirements are presented for both the variable voltage/fixed frequency and variable voltage/variable frequency power conditioning systems. It is concluded that the variable frequency controlled system with pulsewidth modulation is potentially the most energy-efficient system. Power conditioners of this type have not yet been built at the power levels required for a high speed ground transportation vehicle, because these systems require advanced technologies to make their size and weight effective.
