As you may be aware, UQ Jobs was temporarily taken offline due to a data security breach at PageUp – our third party recruitment platform.

PageUp’s security consultants have confirmed that they have not identified any further threats and that PageUp is safe to use. Based on the outcome of that investigation and additional security improvements by PageUp to guard against similar incidents in the future, UQ is satisfied with the security of the system and has reinstated access to UQ Jobs.

As a safety measure, UQ requested a reset of all user passwords. In order to protect your personal account details, the next time you login to UQ Jobs, you will be prompted to set a new password. As good practice, UQ recommends that you do not re-use passwords, or use the same password across multiple systems.

More information about the data breach can be found on the PageUp website.

The role

Pulse width modulation (PWM) is a strategy which is used to control magnitude and/or frequency of output voltage in power electronic converters. It varies duty cycle of the converter switches at a switching frequency to achieve desired voltage and/or current waveform with minimum harmonics and ripples. Fast switching transients (which produce high dv/dt and di/dt) generated by power converters interact with parasitic capacitive and inductive couplings in different parts of power converters - including heatsink, cables, and electric motors. These can cause many unwanted problems such as: grounding and leakage currents, shaft voltage and resultant bearing currents, conductive and radiated Electromagnetic Interference (EMI) and over voltages. Current and voltage harmonics at different frequency ranges are generated by Power Electronics systems both at load and grid sides which need to be suppressed by proper active and passive methods.

The Aim

The main objective of this project are to model a three-phase diode rectifier in Simplorer with a DC choke inductor in Maxwell (3-D model in ANSYS) and analyse saturation effects under different load conditions. A correlation between high frequency noise source and high frequency model of an AC motor will be investigated based on 2-D model of an AC motor using Maxwell simulation (ANSYS). It is expected that the research team will build a prototype and perform some tests and measurements to compare with simulation results.

The person

Applicants should have a Master degree in Electrical Engineering, with a very strong knowledge in Power Electronics. The candidate is also required to meet the minimum requirements for entry into the PhD program. The research group is very dynamic and fast moving and hence it is crucial that any candidate is a team player with an independent and professional work ethic. The candidate must be able to demonstrate an appropriate level of English language ability. At least a 6.5 overall and a minimum of 6.0 in each sub-band of the IELTS or equivalent test is required.

Candidates will also need to be aware of and comply with legislation and University policy relevant to the duties undertaken, including:

Remuneration

Tax-free stipends of $27,000p.a are available for 3 years, with the possibility of extending for a fourth year.
