Job Description

Working Hour: Monday - Friday (8am - 5.30pm)

Job Descriptions:

• Design power conversion circuits (PFC, IPM drive, SMPS, gate drive, DC link) for inverter AC systems.
• Perform circuit simulation to validate waveforms, stress points, and thermal performance.
• Conduct worst-case analysis, derating calculations, and protection scheme design.
• Develop and review PCB layout for high-power, high-noise environments:
  – creepage/clearance
  – EMC suppression
  – thermal spreading
  – current loop minimization
• Validate prototypes through bench testing, reliability tests, and safety compliance testing.
• Support certification tests (IEC 60335, UL 60730, EMI/EMC standards).
• Collaborate with mechanical team on heat sinks, airflow, and enclosure constraints. 

Job Requirements

Education Background : Bachelor’s or master’s in Power Electronics, Electrical Engineering

Experience : Min 5–10 years in power circuit design for inverters, motor drives, or HVAC systems

Required Skill :

• Deep understanding of inverter topologies (single/3-phase), DC bus design,
  IGBT/MOSFET switching.
• Design of protection circuits (OCP, OVP, OTP), gate driver optimization.
• EMI filtering, harmonic suppression, and compliance with IEC/GB standards.
• Familiarity with thermal modelling, heatsink selection, derating under stress.
• Ability to guide layout for high-voltage safety (creepage, clearance).
• Ideally has experience qualifying products for mass production.
