Abstract: A vehicle is equipped with a main drive system and an electric assist drive system which is actuated by the operator when the vehicle speed falls below some predetermined speed. A prime mover for the vehicle, in addition to driving two wheels directly through a primary transmission, drives a three-phase electrical alternator. The alternator energizes an induction motor with a torque-regulating control system for independently driving two other wheels of the vehicle to provide greater traction at low speeds. The rotor circuit of the induction motor includes a rectifier bridge which feeds a line-commutated inverter for coupling the slip power back to the stator input. The control system determines the firing angle for conduction of the switches in the inverter to control the output torque of the induction motor as a function of speed. The system includes a shaping network which defines the desired speed-torque characteristic for accelerating the vehicle; and it generates a signal representative of a demand torque for a given motor speed. Another circuit sensing rotor current generates a signal representative of the load torque. A comparison circuit receives the two signals representative respectively of the actual torque and the desired torque for that speed; and it generates an error signal for controlling the firing angle of the switches in the inverter circuit such that the motor and vehicle are accelerated along the torque-speed envelope of the shaping network once the assisting system is actuated. Thus, the control system regulates the output torque of the assisting induction motor as a predetermined function of vehicle speed.

Abstract: A hybrid synchronous motor drive circuit and method operates in one or two or more modes based on the speed of the synchronous machine. In a first mode, the synchronous machine is driven at a relatively low frequency by a current controlled voltage source inverter (VSI). In a second mode, the synchronous machine is driven at a relatively high frequency by a load commutated inverter (LCI) in tandem with the VSI. In the second mode, the LCI acts as the main power source for controlling the machine and determining machine torque and speed. The VSI acts as a harmonic compensator by compensating the dominant harmonic currents fed to the machine from the LCI such that the synchronous machine will see sinusoidal currents and thereby sinusoidal voltages at its terminals. The VSI also functions to provide sufficient reactive power at fundamental frequency so that the thyristors in the inverter are load commutated.
