Journal Article
Spooner, E., Brown, N., Haydock, L., Mebarki, A., & Novinschi, A. (2005). Equivalent circuit modelling of new brushless synchronous alternator. IEE proceedings. Electric power applications, 152(4), 812-820. https://doi.org/10.1049/ip-epa%3A20045040

A new type of brushless synchronous machine has been described in the companion paper 'New brushless synchronous alternator' (Brown, N.L. and Haydock, L.: IEE Proc., Electr. Power Appl. 2003, 150, (6), pp. 629-635.) The machine combines permanent mag... Read More about Equivalent circuit modelling of new brushless synchronous alternator.

Polynomial Modelling of Electromechanical Devices: An Efficient alternative to Look-Up Tables (2004)
Journal Article

Vernier Hybrid Machines (2003)
Journal Article
Spooner, E., & Haydock, L. (2003). Vernier Hybrid Machines. IEE proceedings. Electric power applications, 150(6), 655-662. https://doi.org/10.1049/ip-epa%3A20030909

The vernier hybrid machine is a member of the family of variable-reluctance permanent-magnet machines. It develops high specific torque by means of a magnetic gearing effect but it suffers from low power factor. The construction of the machine is sim... Read More about Vernier Hybrid Machines.

Current Source Thyristor Inverter and Its Active Compensation System (2003)
Journal Article
Spooner, E., & Chen, Z. (2003). Current Source Thyristor Inverter and Its Active Compensation System. IEE proceedings. Generation, transmission and distribution, 150(4), 447-454. https://doi.org/10.1049/ip-gtd%3A20030304

A grid-commutated thyristor inverter based power electronic interface for a direct-drive modular permanent magnet generator in a variable-speed wind energy conversion system is described. The AC/DC/AC power electronic interface consists mainly of a d... Read More about Current Source Thyristor Inverter and Its Active Compensation System.
