THE OPPORTUNITY
We are seeking an experienced Electrical / Power Electronics Design Engineer to join our team and support the design, development, analysis, testing and validation of high-power semiconductor assemblies and power conversion systems.
The role covers the complete electrical design process, from system-level analysis and semiconductor selection through to detailed assembly design, simulation, testing, technical documentation and customer support.
KEY RESPONSIBILITIES
*Analyse three-phase power systems, including six-pulse, twelve-pulse and multi-pulse rectifier topologies.
*Perform transformer analysis, including star-star, star-delta, delta-star and delta-delta configurations.
*Assess harmonics, power factor, commutation overlap, voltage regulation and fault currents.
*Analyse transformer and semiconductor interaction, including leakage reactance, switching losses, reverse recovery and semiconductor stress.
*Design high-voltage series-connected and high-current parallel-connected diode and thyristor assemblies.
*Develop voltage and current sharing networks, including tolerance and worst-case assessments.
*Design RC snubbers, surge suppression and crowbar protection systems.
*Design low-inductance busbars and current paths, considering current density, short-circuit forces, stray inductance and thermal performance.
*Carry out steady-state and transient thermal analysis for convection, forced-air and water-cooled systems.
*Establish design margins, derating strategies and lifetime assessments.
*Support testing, validation, technical investigations and customer requirements through to final technical documentation.
ABOUT YOU
You will be an experienced Electrical or Power Electronics Engineer with a strong understanding of high-power electrical systems and semiconductor applications.
You will have:
*A degree in Electrical Engineering, Power Engineering or a related discipline.
*At least 5 years’ relevant experience in a power electronics or high-power electrical engineering environment.
*Strong knowledge of transformers, power semiconductors and three-phase power systems.
*Experience using simulation tools such as SPICE and PLECS.
*The ability to perform first-principles engineering calculations and technical investigations.
*Strong analytical and problem-solving skills, with the ability to work independently and take ownership of complex engineering requirements.
*Good communication skills and the ability to work with customers and cross-functional teams.
Experience in one or more of the following would be advantageous:
*Industrial rectifiers
*HVDC systems
*Marine propulsion converters
*Pulse power systems
*Fusion energy equipment
*Rail traction or FACTS systems
The successful candidate will be capable of taking a customer requirement from AC system and transformer analysis through semiconductor selection, stack and protection design, thermal verification, busbar design, testing and final technical documentation.
