Directly adds tangible value to the organization by bringing modern power electronics related technologies, new concepts, circuit topologies, magnetic components design, and control schemes.  Provides strong technical leadership based on rigorous education/training, product development experience, and good track record. Provide technical mentoring to junior engineer and lab technicians. Strong individual contributions in the new product development, system architecture, circuit analysis, and product packaging related to modern precision SMPS power supplies are expected. Evaluate various power converter topologies to achieve optimal cost/ performance design tradeoff. Select/design and evaluate various power electronic components including controller (analog or digital), power switching devices (MOSFETs, IGBTs, and / or wideband gap devices), inductors, transformers, capacitors, current sense elements diodes, etc. to support power converter design. Conduct worst case analysis to establish that designs will function per specifications over the intended operating range. Ability to guide PCB designers and Mechanical Designer for developing UL compliant circuit boards and enclosures for successful operation in highly noisy environment.


Include the following. Other duties may be assigned.

  • Evaluate various power circuit topologies to achieve the optimal cost/ performance trade-offer the particular project specifies to beat the competition.
  • Design and evaluate various Digital and Power Electronic components for state of the art competitive precision AC DC SMPS. Conduct worst case analysis to prove designs will function per specifications over the intended operating range. Conduct analysis and evaluation of system level power electronics system design issues, including AC mains power quality, system efficiency, very low output ripple etc.   Design for compliance to UL, IEC other EMC directives.
  • Ability to guide PCB designers and Mech Designer for developing UL circuit boards and enclosures for successful operation in highly noisy environment.
  • Ability to provide technical mentoring to Lab Technicians and less experienced people.
  • Ability to diligently and very safely work on scientific experiments in power conversion laboratory for power electronics product development.
