Senior Power Electronics Engineer

Job Title: Senior Power Electronics Engineer – Mid-Power SiC Specialist

Location: Woking

Job Type: Full-Time, Permanent

Salary: Competitive, based on experience

Job Description:

Ampere Recruitment is seeking a Senior Power Electronics Engineer specialising in Silicon Carbide (SiC) technology for mid-power applications, focusing on DC-DC and DC-AC converters. This role requires a high level of expertise in simulation-driven design. The ideal candidate will bring hands‑on experience in power electronics, specifically with SiC devices, and a deep understanding of simulation tools to optimize performance, efficiency, and reliability.

Key Responsibilities:

• Design and Development: Lead the design and optimisation of mid‑power SiC‑based power electronic systems, including DC‑DC converters (such as Buck, Boost, and Buck‑Boost converters) and DC‑AC inverters (single‑phase and three‑phase), to meet performance and efficiency targets.
• Simulation Expertise: Perform detailed simulations (thermal, electrical, and mechanical) to evaluate and refine converter and inverter designs. Utilise tools such as LTSpice, PLECS, MATLAB/Simulink, or similar to simulate key aspects such as:
• Switching Losses and Thermal Management
• Voltage Regulation and Power Conversion Efficiency
• Control Loop Stability and Transient Response
• Prototyping and Testing: Develop prototypes and oversee testing of DC‑DC and DC‑AC systems to validate designs against simulations, optimising for EMI/EMC compliance, reliability, and efficiency.
• Cross-functional collaboration: Work closely with teams involved in broader system integration, ensuring DC‑DC and DC‑AC converters fit seamlessly within power systems.
• Documentation: Create detailed technical documentation, including simulation reports, design specifications, and test results, supporting both development and regulatory compliance.
• Continuous Improvement: Stay current with advances in SiC and power conversion technology, applying innovative methods to improve converter efficiency, switching frequency, and thermal performance.

Qualifications:

• Education: Bachelor’s or Master’s degree in Electrical Engineering, Power Electronics, or a related field.
• Experience: 5+ years in power electronics design, with a focus on SiC technology in DC‑DC and DC‑AC applications.
• Technical Skills:
• Proficient in simulation tools such as LTSpice, PLECS, MATLAB/Simulink, with experience in modeling converter topologies (e.g., Buck, Boost, Flyback, and Inverter circuits).
• Strong understanding of SiC power devices, high-frequency switching, gate drivers, and thermal management.
• Knowledge of EMI/EMC requirements, control theory, and closed-loop feedback for converters and inverters.
• Soft Skills: Strong analytical skills, attention to detail, and a collaborative mindset to work effectively within cross-functional teams.

Preferred Skills:

• Knowledge of resonant converter topologies (LLC, ZVS/ZCS) and high-frequency transformers.
• Experience with high-voltage/high-current DC‑DC converters and three-phase DC‑AC inverter applications.
• Familiarity with regulatory standards for power electronics and safety certifications.

This role offers a unique opportunity to shape the future of power electronics with SiC technology. Apply today to join a cutting‑edge team at the forefront of power conversion innovation!
