Latest Patents

One of O'Dwyer's latest patents is focused on control systems for variable reluctance electrical machines. This invention involves a control system for a reluctance motor that drives a load. The output of a reference waveform generator is applied to a power converter through a current controller. The generator's output is determined by rotor position, as detected by a sensor. This system establishes a relative magnitude for motor phase current for every rotor position during the energization period. Additionally, a further control input may determine the absolute magnitude of the motor phase current, subject to the waveform pattern established by the generator. The reference waveforms may be sinusoidal.

Another significant patent by O'Dwyer pertains to power supply systems for reluctance motors. In this system, each phase winding of the motor is connectible across a pair of supply rails by first and second switch means. The first switch means is a fast switch-off device, while the second switch means is a slow turn-off device. In a two-phase configuration, force-commutation of the second switch means may be achieved through a suitable capacitor interconnection between the thyristors switching the respective phases.
