We are seeking a highly skilled PCB Designer specializing in power electronics to join our team. The successful candidate will be responsible for designing and optimizing printed circuit board layouts for high-power conversion systems ranging from 20kW to 40kW. This role requires expertise in PCB layout design, simulation of power electronics circuits, and compliance with safety standards and regulatory requirements.
Job Responsibilities:
PCB Layout Design: Create and optimize PCB layouts using industry-standard design software (e.g., Altium Designer, Cadence Allegro) for power conversion systems.
Simulation: Conduct simulations using tools like LTspice, PSpice or MATLAB/Simulink to verify the performance of power electronics circuits, including converters and inverters, and optimize designs for efficiency and reliability.
High Voltage and High Current Considerations: Ensuring the PCB layout design meets safety standards and regulatory requirements for high voltage and high current applications.
Component Selection: Selecting appropriate components based on the provided BOM and specifications, considering factors such as power rating, voltage, current, temperature, and reliability.
Thermal Management: Implementing effective thermal management techniques to dissipate heat generated by high power components and ensure reliable operation over the system's operating conditions.
EMI/EMC Compliance: Design PCB layouts with consideration for electromagnetic interference (EMI) and electromagnetic compatibility (EMC), employing techniques to minimize noise and ensure compliance with regulatory standards.
Signal Integrity: Ensuring signal integrity is maintained throughout the PCB layout design, especially in high-speed and high-power circuits, by minimizing impedance mismatches and signal distortion.
Collaboration: Work closely with cross-functional teams including electrical engineers, mechanical engineers, and firmware/software developers to integrate PCB designs into the overall system architecture.
Documentation: Create comprehensive documentation including PCB layout drawings, simulation results, Gerber files, assembly instructions, and design validation reports to support manufacturing and testing processes.
Qualifications:
Experience: Proven experience in PCB layout design and simulation of power electronics circuits, particularly in high-power applications (20kW to 40kW).
Proficiency: Proficient in PCB design software (e.g., Altium Designer, Cadence Allegro), simulation tools (e.g., LTspice, PSpice), and signal integrity analysis tools.
Knowledge: Strong understanding of power electronics principles, converter topologies such as buck, boost, buck-boost, flyback, forward, full-bridge, half-bridge, and their operating principles, electrical circuits, semiconductor devices, magnetics, and passive components. Familiarity with control systems theory including feedback, PID control, digital control techniques, and modulation schemes (e.g., Pulse Width Modulation - PWM). Knowledge of transformer and inductor design principles, including core materials, winding configurations, and losses.
Regulatory Compliance: Familiarity with safety standards and regulations governing high voltage systems (e.g., UL, IEC).
Problem-solving Skills: Ability to troubleshoot and resolve PCB layout issues related to power distribution, thermal management, and signal integrity.
Education: Master's degree or Bachelor's degree in Electrical Engineering or related field. Additional certifications or coursework in power electronics and PCB design are advantageous.
Attention to Detail: Meticulous attention to detail to ensure the accuracy and reliability of the PCB layout design, considering factors such as component placement, routing, and mechanical constraints.
