• ### Editorial Electrical systems in transportation

Publication Year: 2011, Page(s):1 - 2
| | PDF (62 KB)

The launching of this new IET Journal comes at a time when we are witnessing significant activity in the use of electrical systems across all the major transport sectors. The motivation for this is derived predominantly from enhanced performance benefits and from political/regulatory pressures to reduce carbon-based fuel consumption and associated emissions. These pressures will obviously continue... View full abstract»

• ### Modelling, design and optimisation of a battery charger for plug-in hybrid electric vehicles

Publication Year: 2011, Page(s):3 - 10
Cited by:  Papers (13)
| | PDF (730 KB)

A PowerPC-centred 110 VAC/2.5 kW full-bridge isolated battery charger was developed for the plug-in hybrid electric vehicle (PHEV). Genetic algorithm was adopted to optimise the system key parameters. Phase-shift-based operation modes were analysed in detail. The system-level safe operational area and other practical design considerations were discussed in detail. Experiments validated the design ... View full abstract»

• ### An effort to formulate frequency modulation constraints in ship-electrical systems with pulsed loads

Publication Year: 2011, Page(s):11 - 23
Cited by:  Papers (3)
| | PDF (1109 KB)

One of the most significant power supply quality problems in ship electric networks is frequency modulation. This is a phenomenon most frequently met in extensively electrified ships and it is caused by the operation of certain electric loads, known as pulsed loads, which require high power repeated on a regular or random basis. To the best of the authors` knowledge, no well-based theoretical ... View full abstract»

• ### Choice of optimal voltage for more electric aircraft wiring systems

Publication Year: 2011, Page(s):24 - 30
Cited by:  Papers (9)
| | PDF (444 KB)

Increased electrical power demands are being experienced on the new generation of aircraft due to an increased reliance on electrical technology such as air conditioning, de-icing systems and electrical flight control actuation. Distribution of power at higher voltages is therefore now being seen in modern aircraft to avoid the penalties incurred due to high wire weights. Voltages have increased p... View full abstract»

• ### Multicore simulation of an ungrounded power system

Publication Year: 2011, Page(s):31 - 40
Cited by:  Papers (3)
| | PDF (978 KB)

An approach to partition power system simulations formulated in mesh currents as variables is presented. Time-domain simulations of large-scale power systems are notoriously slow owing to the system order and amount of time-varying components. A common approach to reduce simulation run-time is to partition power systems using Bergeron's travelling-wave model and to simulate the subsystems on a dis... View full abstract»

• ### Modelling an electropneumatic brake system for commercial vehicles

Publication Year: 2011, Page(s):41 - 48
Cited by:  Papers (4)
| | PDF (582 KB)

The safety of vehicles on roadways depends, among other things, on a properly operating brake system. Commercial vehicles such as trucks and buses are equipped with an air brake system that uses compressed air as the energy-transmitting medium. The brake response time is a critical parameter that affects the stopping distance of a vehicle. The existing air brake system in a commercial vehicle has ... View full abstract»

• ### Interactions within heterogeneous systems of uncontrolled rectifiers for aircraft electrical power systems

Publication Year: 2011, Page(s):49 - 60
Cited by:  Papers (1)
| | PDF (1040 KB)

There is an increase in the use of multi-pulse, rectifier-fed motor-drive equipment on board more-electric aircraft. Motor drives with feedback control appear as constant power loads to the rectifiers, which can cause instability of the DC filter capacitor voltage at the output of the rectifier. This problem can be exacerbated by interactions between rectifiers that share a common source impedance... View full abstract»
