Taha MH, Green T, 1995, Single phase tap-changer using GTOs/thyristors, Pages: 721-724
A single phase Tap-Changer using a GTO with antiparallel thyristor to perform switching of one upward or downward transition is presented in this paper. The logic of operation and experimental results for resistive, inductive and capacitive load are described.
Taha MH, Green T, 1995, Drive circuit for a power GTO with an over current protection, Pages: 529-532
A gate drive circuit for GTO thyristor with over current protection was designed and tested. The paper gives a full description and operation for the circuit. Over current protection circuit could be set to allow maximum current flow through the GTO, this value is related to the rating of the device itself. This paper also will improve the understanding of the switching behavior of a GTO thyristor. The Marconi GT224K GTO, was chosen for the test circuit.

Fletcher JE, Williams BW, Green TC, 1995, Steady state efficiency of a synchronous reluctance drive, ISSN: 0963-3308
The performance of a synchronous reluctance drive can be optimized with regard to such parameters as power factor and transient response (or rate of change of torque). Constant current in inductive axis control yields the best transient response and is often termed vector control. Empirical models are derived to consider the effect of different control schemes on such parameters as steady state losses and low speed torque ripple.

Rahim NA, Green TC, Williams BW, 1994, Three-phase to DC converter combining controlled step-down of voltage and bi-directional power flow, Pages: 295-300, ISSN: 0537-9989
A new configuration for a three-phase bi-directional power converter (AC-DC and DC-AC) is presented. The converter is operated as a step-down converter where the output voltage can be controlled in the range of 0 to 1.5 Vph. The power switch configuration is simpler than the conventional anti-parallel bridge used for bi-directional step-down rectification. It has nine controllable switches and twelve diodes. In the rectifier and inverter mode, line current can be sinusoidally regulated with unity displacement factor. This complies with the EN standard on harmonic currents. Synchronous PWM is implemented in a field programmable gate array and regulation of the output is achieved with a PID controller. Simulation and experimental results are provided to demonstrate the effectiveness of the proposed converter system.
Finney SJ, Williams BW, Green TC, 1994, IGBT turn-off characteristics and high frequency application, ISSN: 0963-3308
Use of a parallel MOSFET can provide a method of reducing the turn off loss associated with IGBTs and achieve a composite effect of low on-state loss and low switching loss. The technique discussed in this paper will be able to increase the effective minimum on-time of the device and this in itself can provide a limitation on the switching frequencies that can be achieved.
Reay DS, Green TC, Williams BW, 1994, Field programmable gate array implementation of a neural network accelerator, ISSN: 0963-3308
The use of a neural network to learn the nonlinear current profiles required to minimise torque ripple in a switched reluctance motor (SRM), at low to medium speeds, has been demonstrated using a digital signal processor (DSP). However, the DSP (Texas Instruments TMS320C25) implementation of a neural network in this application is a limiting factor on motor speed (if maximum current profile integrity is to be maintained). Fortunately, the neural network architecture used (cerebellar model articulation controller (CMAC)) is amenable to hardware implementation a point noted by Albus in one of his original papers and evidenced by at least one previous field programmable gate array (FPGA) implementation. Guided by the requirements of the switched reluctance motor application, a prototype accelerator based on a Xilinx XC4000 FPGA implementation of the neural network has been constructed that operates an order of magnitude faster than the DSP implementation.

Green TC, Khater MM, Williams BW, et al., 1994, Five phase switched reluctance motor - design and performance, ISSN: 0963-3308
This paper presents a design and experimental results for a five-phase switched reluctance motor drive. The system improves SR drive performance by increasing the number of phases without increasing the number of switching devices. A comparison is made of the torque speed characteristics of the motor when fed from the proposed converter and an asymmetric half bridge. This study shows that the proposed converter matches the conventional converter over a very wide speed range.
