  • Power conversion and protection equipment

• Assist in the selection and specification of power semiconductor devices.

• Contribute to the design of snubber circuits, protection systems, and auxiliary circuits.

• Help develop electrical schematics and technical documentation.

Simulation & Analysis

• Carry out electrical simulations using tools such as PLECS, LTspice, or similar software.

• Analyse converter performance, power factor, harmonics, fault conditions, and system behaviour.

• Assist with thermal calculations and temperature assessments of semiconductor devices and cooling systems.

• Support the validation of designs against customer and project requirements.

Testing & Validation

• Participate in prototype assembly, testing, and development activities.

• Help investigate technical issues and support root-cause analysis.

• Assist with factory acceptance testing and product validation activities.

• Support continuous improvement of existing products and designs.

Customer & Project Support

• Review customer specifications with senior engineers.

• Support technical discussions and design reviews.

• Assist in preparing reports, calculations, and project documentation.
