- Develop detailed schematics for high-power charging systems, including AC/DC and DC/DC converters, pre-charge circuits, and protection circuitry.
- Design circuits incorporating high-voltage components, such as power MOSFETs (Silicon, SiC, GaN) diodes, and snubber networks for transient suppression.
- Create isolation circuits using opto-isolators and isolation transformers to ensure safe power conversion.
- PCB Layout & Component Integration:
- Translate complex schematics into optimized PCB layouts, addressing high-current traces, controlled impedance, and thermal management.
- Integrate key components including high-power converters, switching regulators, EMI filters, inductors, and capacitor banks into cohesive designs.
- Incorporate microcontrollers, FPGAs, or dedicated power management ICs to implement digital control schemes and smart charging algorithms.
- Advanced Power Electronics Design:
- Engineer high-efficiency switching regulators and power conversion circuits using simulation tools (e.g., SIMetrix, SPICE, MATLAB/Simulink) to predict circuit behavior under varying loads.
- Develop precise voltage regulation, over-voltage, and under-voltage protection mechanisms, along with current limiting and thermal shutdown features.
- Design and optimize EMI/EMC mitigation strategies, including layout techniques, passive filtering, and shielding for robust performance in electrically noisy environments.
- Component Specification & Integration:
- Select and qualify critical components (capacitors, resistors, semiconductors) ensuring adherence to electrical and thermal ratings, reliability, and cost constraints.
- Develop power distribution architectures that include advanced converters, rectifiers, and isolation modules tailored for rapid charging applications.
- Design Documentation & Collaboration:
- Produce comprehensive design documentation including schematics, layout files, and component specifications for review and integration into system-level designs.
- Collaborate closely with cross-functional teams (mechanical design, firmware, system architecture) to ensure seamless integration of the hardware design into the overall charging solution.
