Abstract:
1. A drive system, comprising: a DC bus, a switched reluctance motor (SR motor), a power inverter coupled electrically between the DC bus and the SR motor, the SR motor comprising phases each of which is operable in operational modes, a voltage sensor coupled electrically to the DC bus to sense a DC bus voltage of the DC bus and output a DC bus voltage signal indicative thereof, current sensors, each current sensor coupled electrically to a respective phase of the phases of the SR motor to sense a phase current of that phase and output a phase current signal indicative of that phase current, and a control system coupled electrically to the voltage sensor and the current sensors, the control system configured to control the power inverter so as to activate the phases sequentially in electrical cycles and so as to operate each phase selectively in the operational modes, the control system configured to:
