JOB DESCRIPTION
A Power Electronics Lead for welding power supplies typically focuses on the design,
development, and optimization of power conversion systems that drive welding equipment. This
role involves overseeing the engineering teams working on the power electronics circuitry and
ensuring the performance, efficiency, and reliability of welding power supplies.
Duties & Responsibilities
- Oversee the design and development of high-performance power supplies for welding & plasma
systems, focusing on power conversion (AC/DC, DC/DC, DC/AC). - Design robust and efficient power control circuits, including inverter systems, to deliver stable
current and voltage for welding processes (e.g., arc welding, MIG/MAG, TIG). - Ensure compliance with industry standards and safety requirements for high-power systems.
- Optimize power delivery systems for different welding processes, ensuring reliability, thermal
management, and operational efficiency. - Implement advanced control algorithms (e.g., pulse-width modulation, digital control) to improve
welding performance. - Continuously improve energy efficiency and power factor correction (PFC) to meet evolving
market demands.
D a t e C r e a t e d : P a g e 2 | 3 - Lead R&D efforts to explore new technologies in power electronics (e.g., GaN/SiC devices) for the
next generation of welding power supplies. - Drive innovation to reduce the size, weight, and cost of welding power supplies while increasing
performance and durability. - Oversee system-level testing and validation of power electronics designs, ensuring conformance
to performance specifications. - Collaborate with test engineering teams to define validation protocols for thermal performance,
electromagnetic interference (EMI), and reliability. - Manage project timelines, budgets, and resource allocations, ensuring on-time delivery of power
electronics solutions. - Engage with stakeholders (product managers, customers) to understand market needs and align
project goals accordingly. - Ensure designs meet relevant standards and certifications (e.g., CSA, CE) for industrial welding
equipment. - Address power quality, electromagnetic compatibility (EMC), and safety regulations in the
product design process. - Lead and manage a team of power electronics engineers, driving development from concept
through production. - Provide technical guidance and mentorship to the team in the design and optimization of power
systems for welding equipment. - Collaborate with cross-functional teams (mechanical, software, systems engineering) to integrate
power electronics into the final product. - Lead and manage a team of power electronics engineers, driving development from concept
through production. - Provide technical guidance and mentorship to the team in the design and optimization of power
