Power Electronics Engineer

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.

• 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.

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.
